Hold on a second - I never see the guest itself. I only see the source physical machine. We boot the source system from the virt-p2v-image-builder CD and then fire up a migration. The P2V runs for about 3+ hours. Watching RHEV-M, I see the physical space used in the Export store ramp up. And then later, it's back down to < 1 GB and there is no guest virtual disk or VM or anything. The P2V apparently blows up with the error below and then cleans up all traces of itself, at least in the RHEV export domain. So I don't have any virtual disk to inspect. But c'mon - every Windows system in the world has the directories mentioned below. This cannot be the first P2V attempt on the planet earth from a Windows system to RHEV. As a workaround - maybe we can put in a custom edit to GuestfsHandle.pm, maybe there's a newer version somewhere, maybe there's something procedurally we can do differently. I don't have virtio-win on this Fedora conversion server. Does that have anything to do with the problem? Could the bug be that it reports the error below when the real problem is, firstboot can't find a disk to boot from because it doesn't have the right drivers? And if so, where do I find a virtio-win RPM that will install on Fedora 14? - Greg -----Original Message----- From: libguestfs-bounces(a)redhat.com [mailto:libguestfs-bounces@redhat.com] On Behalf Of Greg Scott Sent: Friday, November 18, 2011 3:06 PM To: Richard W.M.

Well, we tried our P2V again, this time with a copy of virtio-win.iso in /usr/share/virtio-win that I put in by hand. Just like before, it died again after 3+ hours.

Sorry about the editorial comment. It's really a left-handed plea for help. When the P2V fails, it apparently deletes everything it set up, so there is no guest to run virt-inspector. Where do I export LIBGUESTFS_TRACE=1? AFAIK, there isn't any interactive shell where I can do this. I edit virt-v2v.conf, boot the source physical machine from the CD, and click some mouse buttons. That launches virt-p2v-server on the back end in the conversion server. Is there a hook someplace in virt-p2v-server or maybe virt-v2v.conf? And where does the output go? Does it make sense to export that variable in an interactive shell and then launch virt-p2v-server by hand? Searching for "TRACE" in virt-p2v-server shows no occurrences. But maybe virt-p2v-server runs an executable program that looks at that variable? Should I still be using Fedora 14 for conversion server or is it better now to try with Fedora 16? - Greg -----Original Message----- From: Richard W.M.

Why don't I just set up an i386 F16 conversion server and as soon as I know how to capture the trace stuff we can try with it.

Jones Cc: Fredy Hernández; libguestfs(a)redhat.com Subject: Re: [Libguestfs] Virtio-win RPM? I've had good luck using F14 as a P2V server. You should be able to get the trace output by typing this on the cli on the p2v server itself: "export LIBGUESTFS_TRACE=1". Then, when you kick off the p2v conversion, your p2v server will start spitting out tons of debug logging to stout.

But that export is only in the context of the process where you set it, right? So if I export LIBGUESTFS_TRACE=1 in a terminal window and then virt-p2v-server starts up in a different process, how does virt-p2v-server get its copy of that global variable? Here's an experiment - as you can see below, when I export a variable named GREG, another newly created process does not know about it. [root@FedoraP2V ~]# [root@FedoraP2V ~]# export GREG=1 [root@FedoraP2V ~]# echo $GREG 1 [root@FedoraP2V ~]# ssh -l root 0 The authenticity of host '0 (0.0.0.0)' can't be established.

No need for the second line. /usr/bin/virt-p2v-server is started by the p2v client remotely when it connects. All you should need to do on the p2v server is the first line, and then watch the stdout on your screen as the p2v conversion works its magic.

OK, I must be living in the Twilight Zone: Is there another virt-p2v-server somewhere? The above lines don't exist. Should I just put them in?

We tried another P2V with a different physical server today. Just now watching with RHEV-M, I saw the used space in my Export domain drop from 64GB to 55, then 24, 20, and < 1 GB. Right in front of my eyes it all went away. As soon as I can get some guidance on capturing the detailed trace info - see below - we will try another P2V and capture it. Meanwhile, the only diagnostic info I can find are these entries from /var/log/messages: The Nov. 20 machine was a Windows XP workstation. The one from today, Nov. 21, is a Windows 2003 server. The "p2v-server started" message from 06:07 today was me starting it by hand to get the version number top post here.
