Re: [Moosefs-users] Using MooseFS as a VM diskimage storage

[Scoleri, S. <Sco...@gs...>]

It works.  I'm doing it.  Performance isn't great because you can't mount direct io (I think this is a fuse thing) so you cannot use type disk:aio for your guest disk.  You must use file:/<BLAH>/<BLAH>/disk.img.

I have many guests on mfs and migration and other features all work.  I think its completely viable as long as your guest doesn't do a lot of i/o to its image.

Subject: [Moosefs-users] Using MooseFS as a VM diskimage storage

Hi,
I was wondering if anyone has experience with using MFS to store disk images used by Xen or KVM virtual machines?

If yes, are there any known issues with this setup, be it performance or other?
