[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] guest oops in netfront.c
Hi list,
is this the correct place to report oopses? If not, ignore this.
On my testlab system all five paravirtualized linux guests oopsed after
~1d uptime, probably at the same time (log forensics show that all
oopses happened within one hour). There was probably no load at
oops-time. They did not die immediately, the opentwrt-domain survived
enough to run a final "ps" on its "xm console". I suspect my test-pings
finally killed my guests.
Dom0 and Xen did not realize anything (dmesg, xm dmesg, xend.log,
xend-debug.log). But Dom0 seemed less responsive afterwards, at least
via ssh. I could boot all guests again without rebooting Dom0, let's see
how long they'll live ...
I configured one guest with 4 NICs (did not work ;-), maybe that
triggered the oops?
The host is FC6 (xen-3.0.3-1.fc6, kernel-xen-2.6.18-1.2869.fc6), all
guests used the same kernelimage selfcompiled from Fedora's
kernel-xen-2.6.18-1.2849 sources. Hardware is an intel core 2 duo E6600
(conroe?) on an intel G965 chipset.
/nils.
