Red Hat Enterprise Linux 6 supports the use of the following QEMU CPU model definitions: . When booting a Windows guest that uses virtio-win devices, the relevant virtio-win device drivers must already be installed on this guest.

The virtio-win drivers are not provided as inbox drivers in Microsoft's Windows installation kit, so installation of a Windows guest on a virtio-win storage device (viostor/virtio-scsi) requires that you provide the appropriate driver during the installation, either directly from the virtio-win. Download The Law Of Ueki Sub Indo Mp4 here. iso or from the supplied Virtual Floppy image virtio-win.vfd. The vhost-net module is a kernel-level back end for virtio networking that reduces virtualization overhead by moving virtio packet processing tasks out of user space (the qemu process) and into the kernel (the vhost-net driver). Vhost-net is only available for virtio network interfaces.

If the vhost-net kernel module is loaded, it is enabled by default for all virtio interfaces, but can be disabled in the interface configuration in the case that a particular workload experiences a degradation in performance when vhost-net is in use. This example highlights the string that maps to the Ethernet controller with the short identifier 00:19.0. Note that the: and. Characters are replaced with underscores in the full identifier. Information on the domain, bus, and function are available from output of the virsh nodedev-dumpxml command: virsh nodedev-dumpxml pci_0000_00_19_0 pci_0000_00_19_0 computer e1000e 0 0 25 0 82579LM Gigabit Network Connection Intel Corporation • Determine required configuration details. The virsh nodedev-list command lists all devices attached to the system, and identifies each PCI device with a string.

Information on the domain, bus and function are available from output of the virsh nodedev-dumpxml command: # virsh nodedev-dumpxml pci_0000_01_00_0 pci_0000_01_00_0 pci_0000_00_01_0 igb 0 1 0 0 82576 Gigabit Network Connection Intel Corporation • Add the device. SR-IOV Virtual Functions (VFs) can be assigned to virtual machines by adding a device entry in with the virsh edit or virsh attach-device command. However, this can be problematic because unlike a regular network device, an SR-IOV VF network device does not have a permanent unique MAC address, and is assigned a new MAC address each time the host is rebooted. Because of this, even if the guest is assigned the same VF after a reboot, when the host is rebooted the guest determines its network adapter to have a new MAC address. As a result, the guest believes there is new hardware connected each time, and will usually require re-configuration of the guest's network settings.

Using the lspci command, list the newly added Virtual Functions attached to the Intel 82576 network device. Use the virsh nodedev-list command and the grep command to filter the Intel 82576 network device from the list of available host devices. 0b is the filter for the Intel 82576 network devices in this example. This may vary for your system and may result in additional devices. # virsh nodedev-list grep 0b pci_0000_0b_00_0 pci_0000_0b_00_1 pci_0000_0b_10_0 pci_0000_0b_10_1 pci_0000_0b_10_2 pci_0000_0b_10_3 pci_0000_0b_10_4 pci_0000_0b_10_5 pci_0000_0b_10_6 pci_0000_0b_11_7 pci_0000_0b_11_1 pci_0000_0b_11_2 pci_0000_0b_11_3 pci_0000_0b_11_4 pci_0000_0b_11_5. The pci_0000_0b_00_0 is one of the Physical Functions and pci_0000_0b_10_0 is the first corresponding Virtual Function for that Physical Function. Use the virsh nodedev-dumpxml command to get advanced output for both devices.

# virsh nodedev-dumpxml pci_0000_0b_00_0 pci_0000_0b_00_0 pci_0000_00_01_0 igb 0 11 0 0 82576 Gigabit Network Connection Intel Corporation # virsh nodedev-dumpxml pci_0000_0b_10_0 pci_0000_0b_10_0 pci_0000_00_01_0 igbvf 0 11 16 0 82576 Virtual Function Intel Corporation. The following example shows the syntax for the optional,, and elements.

In practice, use either the or element, not both simultaneously as shown in the example... • Add the Virtual Function to the virtual machine. If the CPU lacks the constant_tsc bit, disable all power management features (). Each system has several timers it uses to keep time.

The TSC is not stable on the host, which is sometimes caused by cpufreq changes, deep C state, or migration to a host with a faster TSC. Deep C sleep states can stop the TSC. To prevent the kernel using deep C states append processor.max_cstate=1 to the kernel boot options in the grub.conf file on the host: title Red Hat Enterprise Linux (2.6.32-330.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-330.x86_64 ro root=/dev/VolGroup00/LogVol00 rhgb quiet processor.max_cstate=1. Alternatively, ensure that the guest network is configured to use your bridged network, and that the XML guest configuration file has a element inside the element, as shown in the following example: hvm.

Red Hat Enterprise Linux 6 and 7 require that every guest virtual machine is mapped to a specific hypervisor in order to ensure that every guest is allocated the same level of subscription service. To do this you need to install a subscription agent that automatically detects all guest Virtual Machines (VMs) on each KVM hypervisor that is installed and registered, which in turn will create a mapping file that sits on the host.

This mapping file ensures that all guest VMs receive the following benefits. Register the KVM Hypervisor by running the subscription-manager register [options] command in a terminal as the root user on the host physical machine.

More options are available using the # subscription-manager register --help menu. In cases where you are using a user name and password, use the credentials that are known to the subscription manager. If this is your very first time subscribing and you do not have a user account, contact customer support. For example to register the VM as 'admin' with 'secret' as a password, you would send the following command: [root@rhel-server ~]# subscription-manager register --username= admin --password= secret --auto-attach --type=hypervisor • Install the virt-who packages. If you just subscribed a for the first time, skip this step. If you are adding additional virtual machines, it should be noted that running this command will not necessarily re-attach the same subscriptions to the guest virtual machine. This is because removing all subscriptions then allowing auto attach to resolve what is necessary for a given guest virtual machine may result in different subscriptions consumed than before.

This may not have any effect on your system, but it is something you should be aware about. If you used a manual attachment procedure to attach the virtual machine, which is not described below, you will need to re-attach those virtual machines manually as the auto-attach will not work. Use the following command as root in a terminal to first remove the subscriptions for the old guests and then use the auto-attach to attach subscriptions to all the guests. Run these commands on the guest virtual machine. Hp Deskjet 656c Driver Mac.

Error Description of problem Solution libvirtd Failed to Start The libvirt daemon failed to start. However, there is no information about this error in /var/log/messages. Cannot read CA certificate This is one of several errors that occur when the URI fails to connect to the hypervisor. Failed to connect socket.: Permission denied This is one of several errors that occur when the URI fails to connect to the hypervisor.

Other connectivity errors These are other errors that occur when the URI fails to connect to the hypervisor. Internal error guest CPU is not compatible with host CPU The guest virtual machine cannot be started because the host and guest processors are different.

Failed to create domain from vm.xml error: monitor socket did not show up.: Connection refused The guest virtual machine (or domain) starting fails and returns this error or similar. Internal error cannot find character device (null) This error can occur when attempting to connect a guest's console. It reports that there is no serial console configured for the guest virtual machine. No boot device After building a guest virtual machine from an existing disk image, the guest booting stalls. However, the guest can start successfully using the QEMU command directly. The virtual network 'default' has not been started.

If the default network (or other locally-created network) is unable to start, any virtual machine configured to use that network for its connectivity will also fail to start. PXE boot (or DHCP) on guest failed A guest virtual machine starts successfully, but is unable to acquire an IP address from DHCP, boot using the PXE protocol, or both. This is often a result of a long forward delay time set for the bridge, or when the iptables package and kernel do not support checksum mangling rules. Guest can reach outside network, but cannot reach host when using macvtap interface.

This is actually not an error — it is the defined behavior of macvtap. Could not add rule to fixup DHCP response checksums on network 'default' This warning message is almost always harmless, but is often mistakenly seen as evidence of a problem. Unable to add bridge br0 port vnet0: No such device This error message or the similar Failed to add tap interface to bridge 'br0': No such device reveal that the bridge device specified in the guest's (or domain's) definition does not exist. Warning: could not open /dev/net/tun: no virtual network emulation qemu-kvm: -netdev tap,script=/etc/my-qemu-ifup,id=hostnet0: Device 'tap' could not be initialized The guest virtual machine does not start after configuring a type='ethernet' (or 'generic ethernet') interface in the host system. This error or similar appears either in libvirtd.log, /var/log/libvirt/qemu/ name_of_guest.log, or in both. Unable to resolve address name_of_host service '49155': Name or service not known QEMU guest migration fails and this error message appears with an unfamiliar host name. Unable to allow access for disk path /var/lib/libvirt/images/qemu.img: No such file or directory A guest virtual machine cannot be migrated because libvirt cannot access the disk image(s).

No guest virtual machines are present when libvirtd is started The libvirt daemon is successfully started, but no guest virtual machines appear to be present when running virsh list --all. Unable to connect to server at 'host:16509': Connection refused. Error: failed to connect to the hypervisor While libvirtd should listen on TCP ports for connections, the connection to the hypervisor fails. Common XML errors libvirt uses XML documents to store structured data. Several common errors occur with XML documents when they are passed to libvirt through the API.

This entry provides instructions for editing guest XML definitions, and details common errors in XML syntax and configuration. If libvirtd still does not start successfully, an error similar to the following will be shown in the /var/log/messages file: Feb 6 17:22:09 bart libvirtd: 17576: info: libvirt version: 0.9.9 Feb 6 17:22:09 bart libvirtd: 17576: error: virNetTLSContextCheckCertFile:92: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory Feb 6 17:22:09 bart /etc/init.d/libvirtd[17573]: start-stop-daemon: failed to start `/usr/sbin/libvirtd' Feb 6 17:22:09 bart /etc/init.d/libvirtd[17565]: ERROR: libvirtd failed to start.

If a host is shut down while the guest is still running a libvirt version prior to 0.9.5, the libvirt-guest's init script attempts to perform a managed save of the guest. If the managed save was incomplete (for example, due to loss of power before the managed save image was flushed to disk), the save image is corrupted and will not be loaded by QEMU. The older version of libvirt does not recognize the corruption, making the problem perpetual.

In this case, the guest log will show an attempt to use -incoming as one of its arguments, meaning that libvirt is trying to start QEMU by migrating in the saved state file. However, the command line used to boot up the guest virtual machine using QEMU directly shows that it uses virtio for its bus type: # ps -ef grep qemu /usr/libexec/qemu-kvm -monitor stdio -drive file=/root/RHEL-Server-5.8-32-virtio.qcow2,index=0, if=virtio,media=disk,cache=none,format=qcow2 -net nic,vlan=0,model=rtl8139,macaddr=00:30:91:aa:04:74 -net tap,vlan=0,script=/etc/qemu-ifup,downscript=no -m 2048 -smp 2,cores=1,threads=1,sockets=2 -cpu qemu64,+sse2 -soundhw ac97 -rtc-td-hack -M rhel5.6.0 -usbdevice tablet -vnc:10 -boot c -no-kvm-pit-reinjection. Note the bus= in the guest's XML generated by libvirt for the imported guest: rhel_64 6cd34d52-59e3-5a42-29e4-1d173759f3e7 20152 2 hvm destroy restart restart /usr/libexec/qemu-kvm. If a message similar to the following appears, the problem is likely a systemwide dnsmasq instance that is already listening on libvirt's bridge, and is preventing libvirt's own dnsmasq instance from doing so. The most important parts to note in the error message are dnsmasq and exit status 2: Could not start virtual network default: internal error Child process (/usr/sbin/dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/ default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/ default.leases --dhcp-lease-max=253 --dhcp-no-override) status unexpected: exit status 2 Solution.

This is the most common cause of this error. If the guest network interface is connecting to a bridge device that has STP (Spanning Tree Protocol) enabled, as well as a long forward delay set, the bridge will not forward network packets from the guest virtual machine onto the bridge until at least that number of forward delay seconds have elapsed since the guest connected to the bridge. This delay allows the bridge time to watch traffic from the interface and determine the MAC addresses behind it, and prevent forwarding loops in the network topology. Use of the generic ethernet interface type ( ) is discouraged, because using it requires lowering the level of host protection against potential security flaws in QEMU and its guests.

However, it is sometimes necessary to use this type of interface to take advantage of some other facility that is not yet supported directly in libvirt. For example, openvswitch was not supported in libvirt until libvirt-0.9.11, so in older versions of libvirt, was the only way to connect a guest to an openvswitch bridge. Set SELinux to permissive by configuring SELINUX=permissive in /etc/selinux/config: # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded.

SELINUX=permissive # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted •. It is not possible to export a local directory from one host using NFS and mount it at the same path on another host — the directory used for storing disk images must be mounted from shared storage on both hosts.

If this is not configured correctly, the guest virtual machine may lose access to its disk images during migration, because the source host's libvirt daemon may change the owner, permissions, and SELinux labels on the disk images after it successfully migrates the guest to its destination.
