Hi,
thanks for you improvements.
I updated libvirt with git and tried to passthrough two pci devices to a
linux guest.
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x05' slot='0x01'
function='0x0'/>
</source>
</hostdev>
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x05' slot='0x03'
function='0x0'/>
</source>
</hostdev>
In the guest, only one of them works and after the shutdown of the
guest, i got a segfault on the host.
libvirtd[15363]: segfault at 38 ip 0000000000421164 sp 00007fff59d1dfb0
error 4 in libvirtd[400000+6d000]
I use kernel 2.6.30-4 on the host.
What did i wrong?
It's more a question of what *I* did wrong, probably :-)
Did this work before? With what version? Is there any chance you could
use git-bisect to find out what commit introduced the regression?
If not, please run libvirtd from the command line with LIBVIRT_DEBUG and
post the log file somewhere. Also, the guest log file
from /var/log/libvirt/qemu would help
Oh, and lspci -vvvv
Thanks,
Mark.
