[Xen-users] CentOS 7 domU PV hang while booting after migration

[Karl Johnson <karljohnson.it@xxxxxxxxx>]

Hi,

I've migrated a domU PV from a host to another using offline rsync (ext4 on LVM) and the domU fail to completely boot on the new host. It hangs at the following line but keep running and using 5% vCPU:

         Starting Switch Root...
[    2.570317] systemd-journald[91]: Received SIGTERM from PID 1 (systemd).
[    2.628091] random: crng init done
[    2.724668] SELinux:  Disabled at runtime.
[    2.754091] type=1404 audit(1527618117.711:2): selinux=0 auid=4294967295 ses=4294967295
[    2.803603] ip_tables: (C) 2000-2006 Netfilter Core Team

I have to xl destroy it. The only difference would be Xen 4.6.3 on the old host while the new is on 4.8.3. Is there any way to troubleshoot this issue?

Here's the full boot log: http://pastebin.centos.org/796571/15276192/

Any suggestions would be appreciated. Thanks.

Karl
