Hi,
I am running ubuntu 9.10, with kvm and libvirt-bin, etc. Using virsh, I
can't live-migrate a VM from host1 to host2. It reports a unknown failure.
The VM image is accessible on both source and destination hosts located on a
shared storage using nfs. Image directory is on the same path on both hosts.
The src and destination hosts are on the same subnet. I can connect to
remote host with qemu+ssh but I can't migrate.
my configuration is:
$ uname -a
Linux mahsa1-desktop 2.6.31-21-generic-pae #59-Ubuntu SMP Wed Mar 24
08:47:55 UTC 2010 i686 GNU/Linux
$virsh # version
Compiled against library: libvir 0.7.0
Using library: libvir 0.7.0
Using API: QEMU 0.7.0
Running hypervisor: QEMU 0.11.0
Connect to the local machine's hypervisor as follows and see the
localmachines:$virsh # connect qemu:///system
$virsh # list
Id Name State
--------------------------------
2 VmLinux11 running
3 VMLinux12 running
4 VmLinux13 running
Verify connectivity to the hypervisor of the remote target system
asfollows:$virsh connect qemu+ssh://host2name/system
Attempt the migration as follows:$virsh migrate --live VmLinux13
qemu+ssh://host2name/system
Connecting to uri: qemu:///system
root at host2name's password:
error: Unknown failure
the log file on the source physical host gives this:14:57:13.514:
error : remoteIO:7184 : operation failed: migrate failed: migrate
"tcp:host2name:49161"
migration failed
14:57:13.709: error : remoteIO:7184 : Unknown failure
I disable the firewall on both hosts but it doesn't still work. please help
me.
