Here’s my HCL report.
This PC has a buggy wifi card Realtek RTL8821CE. Its native driver crashes sys-net. I removed wifi device from sys-net settings temporarily & downloaded tomaspinho’s driver by Ethernet. Cloned debian-11 template for sys-net, set the new template in HVM mode and selected Debian kernel instead of dom0 kernel. After installing new driver, PC works pretty well. But suspend doesn’t work.
