What information do you get when you execute these commands?If I enable SVM in the BIOS and boot the PC the OS don't find network device. If I turn the SVM off everythings fine.
What can I try it in this situation?
lspci | grep -i ethernet
ip a
cat /proc/net/dev
09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
Exciting thing. If the BIOS/firmware is up to date, perhaps contact the manufacturer and initiate a replacement? As a workaround, you could also install an additional network card.I think its not about SVM and Proxmox. There are some serious motherboard issue.
