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
Not paying attention to the rest of the mail, I'd just say that kernel had to kill something due to not having enough memory. What are the memory statistics when starting the guest? What's your overcommit configuration?
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>
