KVM failover to another KVM server

[Dan Sheffner]

Both machines have /etc/libvirt/qemu/ubuntuTest.xml present and I get the same error. Do I have to load the xml in the vmserver06 machine?

The XML config files have to be present on both servers.

ok now I have three servers:

1) storage01
2) vmserver05 
3) vmserver06

storage01 one is sharing out /root/vm/ directory through NFS.

/root/vm from storage01 is mounted at /root/vm on both vmserver05 and 06.

I have created a kvm host on vmserver05 and when I do:

 migrate --live ubuntuTest qemu+ssh://vmserver06/system

error: operation failed: failed to parse XML

do I need to put the xml file on vmserver06? in the /root/vm directory?

DRBD is another nice solution to the shared storage issue.

The ability to do migration requires shared storage such as via iSCSI or
SAN or perhaps NAS (NFS).
The storage needs to be visible on both host nodes on the same path.
