------- Comment #5 from joseph.deming@xxxxxxxxxxxxxx 2010-05-20 11:34 -------
I wanted to confirm likely bug in x64 2.6.32-xen kernels for debain sid/squeeze
using very vanilla kernels and install. use scripts to build dom0 and domU
machines and same scripts work on 2.6.26-xen kernel.
Start a Xen DomU and get kernel oops. After attempting to shutdown/restart
any, all following attempts to start DomU's result in 'Error: Device 0 (vif)
could not be connected. Hotplug scripts not working.' Even successful machine
starts cause initial kernel oops. Dump seems to imply necessary drivers are
loaded netfront, blkfront, netxen_nic, etc. Also, if I remove VIF settings
from conf
boot is fine. ioemu vs no ioemu makes no difference, nor does the DomU
kernel booted, I've tried as many 2.6.32 kernels as I have my hands on for
DomU.
I use scripts to manage and build all DomUs and Dom0s so I can assure
configuration is the same between my 3 machines. The older 2 run 2.6.26 dom0
kernels and work correctly using 2.6.32 domU kernels. The new machine cannot
be driven by 2.6.26 dom0 because it has MegaRAID SAS6 hardware which is
incompatible and causes hard reset on boot, 2.6.18 kernel doesn't support this
hardware either.
