Hi
I have a R710 home lab with OL 8.6, OL KVM and UEKR6 working just fine (can create VM's, start, stop...etc.) I just decided to upgrade to UEKR7 and been getting kernel panics since I upgraded to UEKR7. panics occur the second i try to start an VM
below is m kdump output, i believe this is caused by [ 452.691863] RIP: 0010:imulw_ax_dx+0x9/0x10 [kvm]
