annual howto rampage
I often edit the howto in late december. Now is very late december 2023 ;-)
I have gc'd info about NetBSD 8, and the mention of xm.
Specific things I'd like comments on (onlist please, either to check
consensus or because I think others will think the useful/message ratio
is high enough):
- Are there any problems with 4.15?
- Are there any problems with 4.18 (other than timekeeping)?
- Have we crossed over to 4.18 being the standard approach, and 4.15
old? (I think so but don't want to say that without asking.)
Absent comments, I will adjust to say both 4.15 and 4.18 work, modulo
4.18 timekeeping, and that 4.18 is the standard apparoch.
Further for the list:
- Is anyone working on newer xen?
- Is the problem with i386 PV guests under 4.18 about all PV, or just
NetBSD?
And offlist is fine for things to add/update but not so likely controversial or
useful to others:
- URL for PR about timekeeping?
- Can one now boot a NetBSD dom0 via UEFI? If so, is there anything
tricky? If not, is there a PR?
- Is it true that PVH and PVHVM both also require VT-X/SVM just like HVM?
- Still true?
Operation of i386 PVH guests is not reliable.
See [PR 57199](https://gnats.netbsd.org/57199).
- Do we know the hypervisor version that is troubled about the 33rd
grant table entry?
http://gnats.netbsd.org/58395
(And, I have a system I can crash as a 4G dom0 but not as an 8G bare
metal kernel, via zfs, but I think that's about 4G vs 8G and not about
xen, at least so far. But if you are struggling with this also, please
let me know, privately or onlist.)
