...hrough feature seems to work fine when I assign the physical functions of the nic to the HVMs. They respectfully see the PCI devices, load the igb drivers on boot and have network access. However when I switch to using the virutal functions (starting with simple case of ''modprobe igb max_vfs=1'') the HVMs won''t properly boot and end up getting somehow destroyed late in the boot process, just after the igbvf drivers load. I''ve got plenty of data/logs to post, but I wanted to check in to see if anyone has a working scenario before I start throwing bits aroun...

...39;'s cool. Now I have an Intel 82576 dual-port ET Adapter that supports SR-IOV and started configuring everything to enable it''s virtual functions: added pci_pt_e820_access=on to the module line that contains the vmlinuz created igb.conf under /etc/modprobe.d with options igb max_vfs=7 added blacklist igbvf to /etc/modprobe.d/blacklist.conf I was under the impression that I should see some kind of message about MMCONFIG in xm dmesg, but there isn''t anything. I do a xm dmesg | grep -i pci and it finds nothing with MMCONFIG. I guess my next question is what do...

...s fine, as long as enp2s0f1 is the SRIOV card's PF (Physical Function) and the output of ip link show dev enp2s0f1 shows a list of VFs. In the case that you have no VFs created for that device, yoou can make sure this happens by adding the following to /etc/modprobe.d/local.conf: options igb max_vfs=7 BTW, unless you're concerned about the amount of bandwidth available on a single port of your switch, you can use the PF for host networking, and still use the VFs of that same PF for passthrough assignment to guests. > Then I have > > in a guest: > > <interface type=&...

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

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get traffic in vm, but i see packet arriving in the physical interface of the host I tried to do the following to define the vlan In virsh edit <interface ty...
