cluster fs for live migration ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

i have two hosts running SLES 11 SP4 64bit. Both are HP servers.
KVM is 1.4.2, libvirt is 1.2.5

I will have several guests running on both hosts. I'd like to have live migration. I have an attached SAN, so both hosts have access to the vm disk and its configuration.
Do i need a cluster fs on that SAN or is a "normal" fs like ext3 enough if i'd like to have live migration ? I will create for each vm in the host a seperate partition.

Thanks.


Bernd
