I am very impressed and encouraged by this technology.
One question that I've not been able to get any information on is whether
or not iGVT-g will enable the use of Intel Quick Sync Video (QSV) from
within a Xen- or KVM-hosted guest OS.
My use case is that I use a guest OS with a DVR software that transcodes
using QSV, but I also have other guest OS's (that probably do not need QSV.)
Is there any way to use QSV while virtualized, whether dedicated to a
single virtual host or shared?
could you kindly update us a bit in regard to how is it going with the upstreaming?
there was an upstream kernel merge in December, containing the mdev framework aware i915 driver:
does this mean that the latest kernel now has everything it takes to run vGPU on Intel graphics? Or is the upstreaming process still ongoing?
also there is a separate iGVT-g qemu repository. But for the mdev-based version, is any qemu modification required (i.e. are you preparing patches for upstream qemu as well)?
and about the guest drivers, as the ambition was I guess to be able to use native ones, does that mean that there will be no changes and the drivers currently available will do?
I know Haswell support was removed from the 2016q3 release of gvt. I was
still able to get my Haswell box to run it on the Ubuntu iso. On a lark, I
fired up fedora 25 and pulled the 4.10-rc4 kernel out of rawhide.
I was able to boot the kernel and modprobe kvmgt (which also loaded
vfio-mdev). There was no /sys/kernel/vgt folder available however. I know
vfio-mdev won't work on Haswell, but is there anyway to still use vgt like
in the 2016q3 release?
Thank you for IGVT-G, great job!
i was wondering what's the latest status on Spice support? searching the
list i noticed that it was in planned staged, what's the latest status now?
Hi iGVT-g team,
I'm forced a issue.
Now I'm forced a issue that I got Code 12.
This time I'm using C236 WSI4-85 as test platform.
(Which CPU is E3-1585 /w Iris Pro P580)
Already tried Ubuntu 14.04.5 server, but I got Code 12 on Windows 7 guest
after installed driver.
The boot flag is:
BOOT_IMAGE=/vmlinuz-4.3.0 root=/dev/mapper/os-root ro console=tty0
net.ifnames=0 biosdevname=0 rootdelay=90
i915.hvm_boot_foreground=1 i915.enable_cmd_parser=0 loglvl=all
guest_loglvl=all conring_size=4M noreboot nomdmonddf nomdmonisw
and QEMU command is:
qemu-system-x86_64 --enable-kvm -M pc -m 14336 \
-machine kernel_irqchip=on -bios /usr/bin/bios.bin \
-hda /home/ak/test-intel.img \
-vgt -vga vgt -vgt_low_gm_sz 192 -vgt_high_gm_sz 512 -vgt_fence_sz 4
When I set i915.vgtbuffer=1 and i915.hvm_boot_foreground=0, and set
-display sdl on QEMU, I got white screen on QEMU compositor.
If i turn off vgt buffer and set i915.hvm_boot_foreground as 1, the SDL
shows, but the real monitor didn't show, and I got Code 12 on P580 when
check at Device Manager on Windows 7 guest.
But these doesn't happen before. any suggestion?
