Re: [vfio-users] PXE boot failed if GPU mounted.
Hmm...That's strange. I just test PXE boot again with GPU mounted, but this time is successful (using Tesla P4). And QEMU version still 2.11. But previously it's not working. Perhaps the OS was not doing system update yet at previous installation. I'll take looking at this. Sorry about bothering. Sincerely, Eddie. Eddie Yen 於 2019年5月21日 週二 上午10:00寫道： > Yes.

Re: [vfio-users] PXE boot failed if GPU mounted.
Yes. The QEMU version is 2.11.2 (qemu-2.11.2-4.fc28) How can I doing the separate test by using QEMU 4.0?

Re: [vfio-users] PXE boot failed if GPU mounted.
Hi Alex, Here's VM profile. Basically this VM is created from virt-manager, and guest OS is Ubuntu so no need to add capabilities for Windows environment. https://pastebin.com/VZM63ZsC And GPU for this VM is Tesla P100. But we also found the same issue on another GPU which is Tesla P4.

[vfio-users] PXE boot failed if GPU mounted.
Hi everyone, I'm not sure it's VFIO or pure KVM issue on here. Now we have one GPU server which contains few Tesla GPUs. Installed Fedora 28 and using VFIO to passthrough GPU into VM. Everything is OK, except one annoying things that we using PXE to install guest OS. But PXE can't get any DHCP IP if GPU mounted. We have to un-mount GPU first then re-mount once OS installation completed. For PXE, we use host bridge to connect host VLAN, then let PXE boot vnet going to connect that bridge. I'm not sure the root cause, probably from PCI setup inside VM. Does anyone have idea? Many thanks, Eddie. ___ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
