Title:
Kernel oops in kvm host if using vhost_net in guest (18.04 HWE)
Status in linux package in Ubuntu:
Expired
Bug description:
If I run a KVM guest with a network using the vhost_net driver, I get a
kernel oops with a NULL reference error. It happens randomly. I run a GPU
passthrough setup with windows 10 but I can leave that up 24/7 as I am passing
through a raw ethernet card. Any other virtual machine using the vhost_net
driver will result in a crash in 12 hours or less. I've attached the dmesg that
I captured with kdump. I am not sure when this bug was introduced.
