hi everybody
a windows kvm guest would not start, process gets killed with:
Out of memory: Kill process 21984 (qemu-kvm) score 44 or
sacrifice child
I really don't know where/what I might be missing, config
seems fine, everything looks ok - I only am not sure, do I
need to first stub a SR-IOV device like regular passthrough?
I'm trying sr-iov, having one NIC left to the host and the
second give to a pool.
Then I have
in a guest:
<interface type='network'>
<mac address='52:54:00:99:df:43'/>
<source network='passthrough-pool'/>
<model type='rtl8139'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x07' function='0x0'/>
</interface>
and the net:
<network>
<name>passthrough-pool</name>
<uuid>dd5b4aa3-7c46-4874-a17f-6c0582738bd5</uuid>
<forward mode='hostdev' managed='yes'>
<pf dev='enp2s0f1'/>
</forward>
</network>
