[Xen-users] domU crashes about a minute after migration
Hi guys,
I''ve got a weird issue here, which I''m stuck with:
When I migrate a domU (PV) from one server to another (both identical hardware
and software), it takes about 40-60 seconds after which the successfully
migrated domU simply crashes.
Nothing suspicious can be spotted in dmesg, "xl dmesg", any log files
or the VNC console. It simply stops.
First I thought it might be wallclock related, so I made sure that hardware time
and system time on both machines are in sync (using NTP). That didn''t
change anything though.
During migration, VNC to one server loses connection, and I can instantly
connect to the target''s VNC console, can do stuff in there; everything
seems perfectly fine. And then poof and it''s dead and removed from
xl''s (or xm''s) list of VMs.
The command used for migration:
# xl migrate migrator 10.200.0.113
(coming from source 10.200.0.112, same broadcast domain, even connected to same
switch)
The environment is:
Intel i7, CentOS 6.0 dom0 with Xen pvops kernels (2.6.32 from Jeremy [1], or
2.6.39 from Konrad [2]; references at the bottom), Xen 4.1.1.
Both machines are running exactly the same versions of everything. The
domU''s image is shared via NFS. (Tried with GlusterFS, too, with the
same result.)
DomU: tested with both CentOS 5.6 and 6.0 x86_64, PV; exactly same behaviour,
even with non-PVops Xen-enabled kernel from CentOS
Certainly it''s something really simple, which I''m missing. Any
pointers? Configuration and logs below.
Thanks guys!

Re: [Xen-users] domU crashes about a minute after migration
Hi again,> I''ve got a weird issue here, which I''m stuck with: > When I migrate a domU (PV) from one server to another (both identical hardware and software), it takes about 40-60 seconds after which the successfully migrated domU simply crashes.I can answer this myself now, in case anybody else runs into the same issue: My guest-kernels had this set: CONFIG_XEN_WDT=y From my understanding this requires that /dev/watchdog be fed by a watchdog daemon in set intervals, and if that''s not the case, the Hypervisor will terminate the guest. Interestingly, this only seems to become relevant after migration, which doesn''t quite make sense. The effect after creation or migration should be identical. Anywho... setting this to CONFIG_XEN_WDT=n (or =m) resolves this problem. I can now happily migrate domU''s back and forth, and they don''t terminate any more. (On an unrelated side note: I had to apply a blktap2 "cleanup" patch [1] to be able to migrate the domU back to the host where I migrated it off from, because otherwise remaining tapdisk2 processes would cause the migration to fail and the domU to crash.)
