Look into "AMD reset bug". I'm pretty sure it affects cards RX5* and up (inc. Vega).
no, it's not the reset bug
now both work but:
Hi everyone,
I passthroughed my GPUs successfully with Proxmox (above picture) but there are some problems, wish you guys can help me fix it:
1: When my host is reset or shutdown, I have to unplug the HDMI cables. If not, I cant start the VMs (the VM with HDMI unplugged), with error:
Failed to mmap 0000:27:00.0 bar 0. performance may be slow....
and when GPU driver loaded with windows the VM will be freezed, but host not. If I unplug the HDMI cables when the host is shutdown, then leave it headless, everything is ok, I can check through RDP, then plug the HDMI cables to VMs are fine too, no freezed. But you know it is very inconvenience, I want a way to fix it. This problem does not occur with Esxi but Proxmox. I switched to Proxmox because it's very easy to passthrough mouse and keyboard, in Esxi I have to passthrough all of USB controller and have to buy a USB PCI-E card for second VM, it is inconvenience too.
I also used:
echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nvidia" >> /etc/modprobe.d/blacklist.conf
and check in:
lspci -v
I saw GPUs was using: Driver of Vfio. So I think this is not a problem. I feel the host still eat the GPU although it cant load the driver
2: I want to use my CPU host name not the Common "Ugly" KVM
when I tried:
cpu: host,hidden=1,flags=+pcid
args: -cpu 'host,+kvm_pv_unhalt,+kvm_pv_eoi,hv_vendor_id=NV43FIX,kvm=off'
Yesterday, it worked fine, it showed the real CPU name
But today, it gave me:" host doesnt support reqested feature: CPUID.01H.ECX.pcid (bit 17) then it BOSD itself during windows load. How so ?
And can I affinity the CPU core/thread to VMs ?
3: I want to add new NVME SSD to VMs to use on VMs but is there any way to VMs use on the same Drive ?, like network Drive. I saw on net cafe they boot windows through the LAN and run games on it, the computers dont need a Hard disk.
4: can I limit bandwidth on VM's vlan ?
5: Very inconvenience, the Proxmox OS changed my time in BIOS automatically, it made the time slower than 7 hours, when I changed in BIOS then load Proxmox, it changed again. It made the VM wrong time too, I really hate it.
6: Is there a way to use Parsec without a HDMI dummy or monitor ? some people told me that use a resistor on DVI port but mine is DVI-D :').
My testing system:
CPU: Ryzen 5 1600X 6 core/12 thread
Main: X370 Gaming K4 latest BIOS AGESA
1.0.0.6
RAM: DDR4 16 GB
GPUs: RX 470 + RX 580
PSU: CM V1000
a bunch of SSDs and HDDs
Thanks in advance!
