It basically makes no difference using VirtIO SCSI or any other controller with VirtIO Block.
#Does processor matter for os x vm driver#
Documentation states that performance-wise best option for hard disk is SCSI driver (newer than VirtIO Block) with VirtIO SCSI controller and IO Thread on, but MacOS doesn't recognize the disk if using anything else than VirtIO Block. PS what is io_uring you mention? Do you mean IO Thread option on Hard disk? I tried with and without it and it seems to make no difference.
But after a few minutes of work it starts again.
There is something wrong if I'm getting much better ssd results without caching.Īlso, there is another issue that I see now in MacOS, I have stutter and glitches when watching youtube videos, and generally when I put some strain on the ssd the whole system starts having these glitches and it can only be partially solved by restarting. If trim isn't working properly how come there are not more mentions of this on the forums? What I see in every tutorial on creating MacOS VM in Proxmox is to set writeback (unsafe) and check the Discard option (for trim to function), and this is coming from people who also use nvme ssd like me.
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=pt amd_iommu=on video=efifb:off" I'm guessing there is something wrong with PCIE or even with my MBO, but is there a way to test this or some settings I should do in Proxmox?Īrgs: -device isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" -smbios type=2 -device usb-kbd,bus=ehci.0,port=2 -cpu Penryn,kvm=on,vendor=GenuineIntel,+kvm_pv_unhalt,+kvm_pv_eoi,+hypervisor,+invtsc,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+avx2,+aes,+fma,+fma4,+bmi1,+bmi2,+xsave,+xsaveopt,checkĮfidisk0: local-lvm:vm-100-disk-1,size=4M I didn't test USB speeds with any tool but copying a 8GB from a USB stick file felt fast as expected. With Novabench I noticed that something is wrong with SSD - I got around 200MBs write and 4000MBs read on first test, then every other test was much worse - down to 100MBs write and 300MBs read. GPU Compute score is around 35000 which is also 10-15% lower than expected, but this is not important for me.

On Geekbench 5 I get around 950 single core speed and 6200 multi-core, while on the same system with a bare-metal hackintosh install I was getting 1070 single and 7000 multi-core. Set VM RAM to 30Gb, if I set it to max 32Gb VM won't start Set CPU cores to 16 (either 2 sockets / 8 cores or 1 socket / 16 cores, results are the same). Can't tell if keyboard is actually laggy, it feels only the mouse is the issue Then I passed through the whole USB3.0 controller PCIE device, also works but lag is the same. USB passthrough working but cursor very laggy (Logitech unifying receiver), regardless if I passthrough device or port. setup GPU passthrough (blacklisted Radeon drivers, set display to none) installed Proxmox and then Big Sur VM on same Samsung 970 Evo NVMe SSD (chose xfs as file system) Ryzen 2700X, Gigabyte Aorus M B450, 32GB g.skill 3200mhz RAM, Sapphire RX 580 8gb 4K playback from Youtube doesn't affect the system in this way, but there is a problem with Realtek network controller which is stuck at 10Mbit, and I had that problem earlier on hackintosh install so it might be a hardware problem.

For example if I play a 4K movie file everything becomes very sluggish, cursor lag gets so bad I can barely click on buttons. I managed to get Big Sur up and running on Proxmox v7, and while I'm getting acceptable results on CPU and GPU benchmarks, the SSD and overall performance is just terrible.
