Dear Xen developers,

I would like to ask if the following fix can also be included in Xen 4.17.6 (and eventually in the Xen versions after 4.17.6 that don't have the fix) :

https://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=dd05d265b8abda4cc7206b29cd71b77fb46658bf

This bug causes a boot loop in nested virtualization environments (for instance nested environments that use VMware Workstation), making Xen unable to start. It was introduced in version 4.17.3 and the fix has already be included in 4.19(.2) and 4.20(.0) and woud be planned to be included in Xen 4.18.6 in the coming weeks.

Even though Xen 4.17 is in security-only support, this is an issue that blocks testing and usage for users and projects such as Alpine Linux.

I am a student using Xen in a nested setup for Virtal Machine Introspection (VMI), and including this fix in 4.17.6 would really help avoid these problems for others in a similar case.

Best regards,
Julie Ngamia
