Doesn't look like client related, moving to Hans, who has been working more than I did on file-xfer. OK, I played around with the VM a bit more, and it seems that it'll hang if I fill the filesystem using any means (dd if=/dev/zero of=... also works). Most probably the crash has nothing to do with spice. Sorry for the misleading bug report. I'll try to investigate what exactly is happening, but not today, I've had enough testing for the moment. Hi, So it seems that we've 2 different issues here, 1 is the client and the agent loosing sync, as shown by this message: > May 30 12:32:52 localhost spice-vdagentd[491]: chunk port 2065 out of range > May 30 12:32:52 localhost spice-vdagentd[491]: AIIEEE lost spice client > connection, reconnecting > May 30 12:32:52 localhost spice-vdagent[2318]: file-xfer: Removing task 5 > and file /home/liveuser/Downloads/testday-20130530-i686.iso due to error This means the file drag and drop will fail, but it does not explain the guest hang / crash. I've spend quite a time debugging the above issue a while back, as I also hit it in my own testing, so this is fixed upstream by this commit: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=75c439bc65c07d76f5e74c734ed5432bc6114a3b I did not think about adding this fix to the Fedora packages, since it will only trigger when using file xfers but since we support file xfers now in Fedora, we should add this fix to at-least F-19 qemu, and it certainly can't hurt for F-18 either. Changing component to qemu.

Sorry for the > misleading bug report. Well it was a useful bug report, see above. Please file a new bug for tracking the hang on file-system filling issue (once you've more details). Could it be that you're using qcow2 and the host fs is getting full ? Regards, Hans (In reply to Hans de Goede from comment #3) > Could it be that you're using qcow2 and the host fs is getting full ? I'm running from the LiveCD, so I don't think the disk image matters. Anyway, the disk image has raw format, and the host fs has plenty of space. > Well it was a useful bug report, see above. Please file a new bug for > tracking the hang on file-system filling issue (once you've more details). I get the same behaviour for both the i686 and x86_64 variants, but I can't get kdump to work, so it's unlikely that I'll be able to provide more details. I'll file a bug if something useful turns up. On the serial console (unfortunately the top has scrolled off): [ 444.400054] Aborting journal on device dm-0-8.
