Comment 1 Justin M. Forbes 2016-02-18 11:29:27 EST
How much memory is in the VM? Where is the swap storage in this case? Seems like a general network is causing issues here. Do retransmits work?
Comment 2 David Shea 2016-02-18 11:49:57 EST
1GB of memory in the VM. Swap is a 1GB LVM volume on a virtio disk backed by a 10G qcow2 file on the host.


The kernel panic happened in one of the anaconda kickstart-tests run in jenkins, and the other 51 jobs using the same network config worked fine (kernel-wise, at least), so as far as I know everything is ok as far as network.
Comment 4 David Shea 2016-02-18 13:06:43 EST
Actually, the ftp test is, I think, the only one that tries to fetch data from off the redhat network, so maybe it is a retransmit issue. I have no clue if retransmits work.
Comment 5 David Shea 2016-02-18 13:58:42 EST
Never mind, this last run had 6 panics in different tests. One of them appears to be unrelated (suspicious RCU usage in an NFS mount, I'll file a new bug for that), but the other five are all page allocation failures. Let me know what information I can provide. I can attach the full virt-install.logs from the failing jobs if that would help.

This is now with kernel-4.5.0-0.rc4.git1.1.fc24.x86_64
