Re: [libvirt] [PATCH 0/8] Various KVM PCI device assignment improvements
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?
Greetings
Hi,
Here's a fairly mixed set of KVM PCI device assignment
improvements:
- Add hotplug support
- Allow PM reset on multi-function devices
- Allow Secondary Bus Reset even if it causes other devices to be
reset, so long as those other devices are in use by the same
VM or are unused
- Re-attach devices when the guest shuts down
- Properly detect versions of QEMU without -pcidevice support
Cheers,
Mark.
