Dear list, when I try to convert the (working) command /usr/bin/qemu-system-x86_64 \ -drive file=/dev/xen_vol/xen_ca,cache=none,if=virtio,boot=on \ -net nic,model=virtio,macaddr=00:16:3E:04:F5:6D \ -net tap,ifname=tap1 -m 256 -name ca \ -vnc 10.0.0.100:4 -daemonize -k de into an xml file: <domain type='qemu'> <name>ca</name> <uuid>dfef3884-d7a9-f6cf-5204-1615963cc0e8</uuid> <memory>262144</memory> <currentMemory>262144</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64'>hvm</type> </os> <features> <acpi/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='block' device='disk'> <driver cache='none'/> <source dev='/dev/xen_vol/xen_ca'/> <target dev='vda' bus='virtio'/> </disk> <interface type='ethernet'> <mac address='00:16:3e:04:f5:6d'/> <target dev='tap1'/> <model type='virtio'/> </interface> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5904' autoport='no' listen='10.0.0.100'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> </devices> </domain> Then it stops to boot while haning on "Loading Grub Stage 2". Additionally, the keyboard encoding "de" is missing.

[libvirt-users] Can not restore domain from a shared state file
by Zhang Qian 16 May '10

16 May '10

Hi, I have two KVM host: h1 and h2, both of them mount an NFS directory as a shared storage. I can save (virsh save <domain> <file>) a domain in h1 to a state file in the shared storage successfully, but failed to restore it from h2 with the following error message: # virsh restore testRes.dat error: Failed to restore domain from testRes.dat error: operation failed: failed to start VM I can always restore it from h1, but sometimes works for h2 (wait for a while, then "virsh restore" command may succeed in h2). I guess the state file generated by "virsh save" command is not intact from h2 point view, may be cause by the cache of NFS server? Any suggestions will be really appreciated, thanks in advance! Regards, Qian
