[Xen-devel] stale hypervisor info in HVM after migration

[Olaf Hering <olaf@xxxxxxxxx>]

During boot of a HVM domU, the running hypervisor ist recorded in DMI and dmesg:

crash> dmesg | grep -m1 Xen
[    0.000000] DMI: Xen HVM domU, BIOS 4.7.2_02-36.1.1284 08/28/2017

But after migration to another host, that info is not updated.
Is there a chance to update that info in the kernels "resume" path?
It would probably be ok to just do a printk in case DMI is a static string.
