Running inside Ubuntu VM on Proxmox (Hauppauge WinTV-QuadHD) #132

Closed samip5 closed 2 years ago

samip5 commented 3 years ago

I'm seeing wierd issues with the driver or my card, as it was working fine previously and I don't know what changed. My vm host is running Promox 7 with intel_ionmu enabled and the DVB card passed though to the VM.

dmesg log snippet:

This is an issue that crops up for some people on occasion, depending on their system. Have you tried any of the reported working solutions? Like the dma workaround kernel parameter or forcing your pcie slot to gen 1 in the bios?

b-rad-NDi commented 2 years ago

Also, we don't really support use of the hardware in vm's. It works for a lot of people, but there is a lot involved and things can break even in so called "pass thru" modes

Yeah, I don't know what it actually was, but after a fresh Ubuntu 20.04 and the PPA driver aka mediatree kernel, it works again in non-vm. None of the reported "working" solutions worked for me before fresh install, as I did try the dma workaround too. I tried before fresh installing pretty much all of the workarounds (except forcing pcie slot), in a VM and non-vm environment but no dice.
