[libvirt-users] Problems running virtual machines after an upgrade
Hi all, I upgraded qemu-kvm and libvirt to the new versions qemu-kvm at : 1.0 libvirt at : git version 0.9.10 I lost the original machines but the xml files were are all present (it is not showing up in virsh list --all) But when I import an xml I get an error: Attached is some information which might be helpful Can someone help please ? If this is a compatibility issue please can someone tell me which is the latest version of qemu-kvm and libvirt combination which will work ? I cannot use qemu plain since it does not yet support boot from scsi thanks ----------------------------------------------- $ sudo virsh list --all Id Name State ---------------------------------------------------- $ lsmod | grep kvm kvm_intel 112920 0 kvm 280656 1 kvm_intel $ /usr/local/sbin/libvirtd --version /usr/local/sbin/libvirtd (libvirt) 0.9.10 $ ./qemu-system-x86_64 --version QEMU emulator version 1.0-bcv (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice Bellard $ sudo virsh define ./debian.xml error: Failed to define domain from ./debian.xml error: unknown OS type hvm $ cat debian.xml <domain type='kvm'> <name>debian</name> <uuid>0aab8869-ff87-14ce-a00b-944cdca7acf7</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu cpuset='6-7'>2</vcpu> <cputune> <vcpupin vcpu='0' cpuset='6'/> <vcpupin vcpu='1' cpuset='7'/> </cputune> <os> <type arch='x86_64' machine='pc-0.14'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <cpu match='exact'> <model>core2duo</model> <vendor>Intel</vendor> <topology sockets='1' cores='2' threads='1'/> <feature policy='disable' name='lahf_lm'/> </cpu> <clock offset='localtime'> <timer name='hpet' tickpolicy='catchup'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/local/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/VIRT/disks/DEBIAN'/> <target dev='sda' bus='scsi'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <disk type='block' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' unit='0'/> </disk> <controller type='scsi' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </controller> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:71:62:f3'/> <source bridge='virt'/> <model type='e1000'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-gb'/> <sound model='ich6'> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </memballoon> </devices> </domain> -- Bhasker C V

Which distro are you using? Did you self-build libvirt?

This might be a case of virsh picking up a different default URI, based on what support you built into libvirt. Try 'virsh uri' to see what your default URI is. If it is not 'qemu:///system', then that explains your symptoms, and using 'virsh -c qemu:///system list --all' will restore your listing abilities. You can export VIRSH_DEFAULT_CONNECT_URI so you don't have to use virsh -c every time.
But when I import an xml I get an error: Attached is some information which might be helpful Can someone help please ?

The versions you have listed should be compatible (there was an issue where older libvirt didn't like the newer qemu 1.0 versioning scheme, but that has been fixed).
$ /usr/local/sbin/libvirtd --version /usr/local/sbin/libvirtd (libvirt) 0.9.10
$ ./qemu-system-x86_64 --version
That's a different executable...

...than what you are testing here. It may be that you are telling libvirt to use the wrong binary, and that might be the source of your error message.

You can export VIRSH_DEFAULT_CONNECT_URI so you don't have to use virsh -c every time. I did try using differnt URIs but did not get this working. I could not see any machines in --all option $ type virsh virsh is aliased to `virsh --connect qemu:///system' $

I am still seeing issues. I just downloaded the git version and the qemu-kvm-1.0 but when compiled did not work Did not work is in the sense as told above The virsh capabilities does not show hvm in the list

Hah I forgot to tell kvm is linked to qemu-system-x86_64 I just went back to libvirt 0.9.1 with qemu-kvm 0.14.1 and thingss are back to normal ; atleast in working condition The main reason I wanted to move to newer versions is that I wanted to use USB 2.0 rather than forced to use USB1.0 in case of the versions of qemu and libvirt i specified. Since this is a production system I think I have to create a backup system and try it out to see if I am able to get this working ... -- Bhasker C V

Hmm, I suspect "1.0-bcv" version is not in the form we expect it to be. The "-bcv" suffix causes this binary to be detected as qemu only, i.e., not kvm capable... Which is wrong, btw, we should be detecting kvm capability by checking -enable-kvm or -disable-kvm options since even plain qemu can use kvm. Jirka
