https://bugzilla.kernel.org/show_bug.cgi?id=217558 --- Comment #8 from Chen, Fan (farrah.chen@xxxxxxxxx) --- Hi Patryk We reproduced this issue with the latest kernel commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master a92b7d26 kernel version: 6.4.0_rc7 When you reproduce, did you create multiple VFs and passthrough all of them to KVM guest? I found that if we only passthrough one VF to guest, the mac is the same as it in host, but when passthrough 2 or more VFs, sometimes only the first VF use the same mac as it in host, other VFs' mac are random; sometimes all the VFs' mac are random. -- You may reply to this email to add a comment.
