Migrating away from XenServer

After this, it would be easier to just copy the actual drive image from XenServer. Just about any tool can convert those un-exported images no problem.
Will you be using Ovirt?

Whatever libvirt is using on CentOS 7. I don't know off the top of my head. Just know that I can manage the local and remote machines via Virtual Machine Manager.

I attempted to move from Xenserver to a Scale cluster, so basically KVM, but I was unsuccessful. I ended up rebuilding all of the VMs.

Like I said, best to actually copy the disk images from the XenServer rather than exporting like you'd think. The export process seems to break things rather than make them easier

There was some wacko way you could copy the raw files from XenServer. You had to enable some option and then it would create an http address you could scp the image from. I forget how it worked.
You also can export in raw format from XenCenter. By default it tries to use iSCSI so if you are on a workstation it may not work. You have to edit the XML for XenCenter and restart it and it will scp (I think it's scp) it to your workstation.

I want to convert two of my hosts to KVM, too… but my choice would be OpenSuSe, for the simple reasons that is more updated and it is a real enterprise distro, not like ubuntu. AFAIK KVM is fully supported.

I am going to use Fedora for my install.

Yes. Tumbleweed specifically.
-
@scottalanmiller no, I will go with Leap. Why Tumbleweed as an host?

Exactly for the reason that you listed.... more up to date.
-
@scottalanmiller but I don't want my host to stop working for an update… OpenSuSe 42.3 seems fairly recent to me.

What does this mean? Why would stop working?

I've seen updates breaking bridge functionality or messing with the VM hardware… an always updated host is a good choice for security and performance, but run VMs on libvirt alpha…

it is said that @scottalanmiller is currently running on kernel 5.0. Stable.
5.1rc0 is planned for deploy tomorrow 00:00 utc.

on centos "plain" repo it is virt manager. enablig the centos ovirt repo you can run ovirt.

That's because it JUST released, so it feels recent. But the real question is, how recent does 42.2 feel? That's the one that would tell you if you'd be happy with the LTS release cycle or not. I don't see much value in LTS releases any longer.

That can happen with LTS the same as rolling, though. Is rolling really at any greater risk of this?
-
@scottalanmiller so, your raccomandation for deploying a KVM host is fedora 26, because KVM it is RH baby and F26 is the most recent one?
-
@scottalanmiller with non-server hardware, 100% yes. I had multiple laptop and desktop pc that weren't able to boot or do basic stuff like loading bash or reading their own LUKS or LVM volume just after an update.
