Re: [libvirt-users] sr-iov on Intel 82576 and rhel 7 - would not work

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> ---- 02:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) Subsystem: Super Micro Computer Inc Device 10c9 Flags: bus master, fast devsel, latency 0, IRQ 40 Memory at dfce0000 (32-bit, non-prefetchable) [size=128K] Memory at dfcc0000 (32-bit, non-prefetchable) [size=128K] I/O ports at a800 [size=32] Memory at dfc9c000 (32-bit, non-prefetchable) [size=16K] Expansion ROM at dfca0000 [disabled] [size=128K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Capabilities: [70] MSI-X: Enable+ Count=10 Masked- Capabilities: [a0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 00-25-90-ff-ff-72-bb-e2 Capabilities: [150] Alternative Routing-ID Interpretation (ARI) Capabilities: [160] Single Root I/O Virtualization (SR-IOV) Kernel driver in use: igb 02:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) Subsystem: Super Micro Computer Inc Device 10c9 Flags: bus master, fast devsel, latency 0, IRQ 41 Memory at dfc20000 (32-bit, non-prefetchable) [size=128K] Memory at dfc00000 (32-bit, non-prefetchable) [size=128K] I/O ports at a400 [size=32] Memory at dfbdc000 (32-bit, non-prefetchable) [size=16K] Expansion ROM at dfbe0000 [disabled] [size=128K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Capabilities: [70] MSI-X: Enable+ Count=10 Masked- Capabilities: [a0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 00-25-90-ff-ff-72-bb-e2 Capabilities: [150] Alternative Routing-ID Interpretation (ARI) Capabilities: [160] Single Root I/O Virtualization (SR-IOV) Kernel driver in use: igb _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
