hope somebody can help with a kind of bizarre issue, only experienced on antergos/arch linux distros (yes, for testing I tried to build also a pure arch linux machine).
Tools used: virtual machine manager (virt-manager), libvirt, KVM, ovmf-git UEFI bios, Windows 10 standard ISO.
So after following a guide in how to setup my system (namely http://dominicm.com/gpu-passthrough-qemu-arch-linux/) everything works flawlessy (installing Windows 10 guest and configuring it, by using the Spice console), until I start to pass my dedicated GPU - an Nvidia GTX 1080.
When I try to boot it, virtual machine manager CPU graph shows that the usage skyrockets to 100% and I have no display output; if I’m patient for around 10-15 seconds, then I will have display output on passed gpu (I see the tianocore splash screen) and the system starts correctly with no performance loss.
I have seen tat this behavior is becoming worst is I assign more memory to the guest OS. Let’s say I have the 10-15 seconds cpu 100% usage/no display output if I assign 8GB ram, 25-30 if I assign 16+GB.
If I assign 2GB of RAM to the virtual machine,boot and display output, it’s quite immediately.
This lead me to think that some sort of bug (tianocore git UEFI bios? libvirt? kernel?).
As I have tested other linux distros, like Fedora 25, Linux Mint 18, Debian Stretch, I am experiencing this “issue” only on antergos/arch.
Any suggestions will be greatly appreciated.
My system info:
Asus X99-E WS
Intel i7 5930K @ Stock 3.5GHZ
32GB DDR-4 2666MHz RAM
Samsung SM951 M.2 SSD Disk
Linux GPU Nvidia GTX 670
VM dedicated GPU Nvidia GTX 1080
Thanks and regards
as pointed out from Joe, please add the scanner IP inside /etc/sane.d/net.conf ; just be sure to put it in a new line without the # in front. EX:
#This is a comment
As you can see, for the sake of testing, do not include the 0 on the last part of your ip (as opposite of what’s suggested by your router).
I have a MFC-L8650CDW from Brother and to make it working successfully I first installed the linux printer driver from their website (http://support.brother.com/g/b/downloadtop.aspx?c=gb&lang=en&prod=mfcl8650cdw_eu_cn) by selecting IP address when asked for the device URI. Then I added my device IP to the sane configuration file mentioned above and restarted my antergos box. If the scanner was still not recognized, I did re-installed it manually using the brsaneconfig4 command.
Please note that before being able to run the printer driver installer, you need the rpm package, which you can find on the AUR as rpm-org (yaourt rpm-org).
My device IP is 192.168.254.30 and I wouldn’t add the 0 before the 30 (192.168.254.030).
