Hey all,
I have a question about a solution for migrate LVM based guests directly
over the network.
So the situation: Two KVM hosts with libvirt, multiple LVM based guests
Want to do: Migrate a LVM based guest directly to the other host over an
secure connection
I know that migration is possible when the VM disks are stored on an
NFS, GFS2 filer/cluster etc.
So would it be possible to do an offline migration directly with netcat
or something like that?
If all you need is offline, you can use scp to copy each volume to the
destination volume. Make sure the guests are shut down when you do that.
It is also possible to do a live migration, but unless the destination
and source are in the same IP subnet, the guests are going to lose
connectivity.
Hello Avi,
so can I simply copy an logical volume to the path of the volume group
with scp?
Yes. Best to enable compression to avoid sending zero blocks.
For the live migration theme, it would be no problem when the guests
looses connectivity, how could be done a live migration?
See the -b option to the migrate command.
I will read a little bit about the live migration theme.
Best Regards
