<div class="moz-cite-prefix">Hi,<br>
<br>
Here we user as third|quorum machine, a VMWare machine. It worked
perfectly as far as it does not host any VM itself.<br>
<br>
To migrate linux machines, we created a new VM on proxmox, booted
it up with a sysresCD and then netcat the whole system from the
xen VM to the new PVE machine.<br>
<br>
Hope it helps,<br>

<pre>Hi,
I'd considered that, but I'm having trouble finding a system that supports VT-d/VT-x.
Any hiccups converting Xen to KVM? I imagine the Windows boxes will move easily enough, just using clonezilla or similar. The rest of my servers are Ubuntu based, and PVM's so I'll need to add a kernel, so I'm looking at <a class="moz-txt-link-freetext" href="http://www.blog.turmair.de/2010/12/xen-to-kvm-or-physical-vmware-migration/" target="_blank">http://www.blog.turmair.de/2010/12/xen-to-kvm-or-physical-vmware-migration/</a>
Any performance issues?

Hi,
we did pretty much the same thing over the past weeks, ie. changing
fom
XEN to KVM (Proxmox) reusing the hardware already in place and
production. But we didn't went down the 2-Node cluster road, what we
did
instead was, that we used an old server machine as a third node, just
for the sake of quorum and not having to deal with all the problems,
that may occur on a 2-Node cluster. No guests on that machine and as
soon as the 3rd production machine was free, we added it to the
cluster
and removed the old one.
I guess performance is not an issue for that 3rd machine, as long as
it
has no guests.
Hope that helps a little,
best regards,
Kurt

<pre>Hi,
We've pretty much made the decision to move from Citrix XenServer
to KVM (Proxmox) for our Virtual solution. Unfortunately, I don't
have all the computers available to me at the start, since
migration will use the existing XenServer computers.
To start, I'll have two servers, using a single iSCSI, in an HA
cluster. Once they are running and some of the virtual machines
are migrated, I can add a third server. Finally, I can add the
fourth server.
Is there anything I need to look out for when creating the 2 server
HA cluster and then converting it to a 3 and 4 node cluster?
Has anyone done this, and created a HOWTO I can follow?
Thanks,
Gerald
ps: Been using Citrix XenServer since Jan 2009. We've had enough
issues with VM disk corruption to haunt me for year (using
LVMoveriSCSI). It's a bloody house of cards.
