I'm guilty of pulling in later Xen source and building it based on the experimental 4.16 packaging. As such this may actually only be an issue for a package version beyond 4.16.0. I'm uncertain which it is, but xen-utils-4.16 appears to need an update to one or more of libxencall1, libxenevtchn1, libxenforeignmemory1, libxengnttab1 and/or libxentoollog1 in order to function. During my initial update I merely updated libxenmisc4.16 and libxenstore4. In this condition something (I suspect xenstored) was rather broken and things were unusable. Notably `xl list` was hanging. I was unable to get VMs started and it felt like everything wanted to explode.
tags 1005176 + moreinfo thanks Hi Elliott, :) This one is really too vague to be able to react to in any sensible manner. Reading it was a fun experience though. It made me think of creating a bingo card with 30 possible things that a bug reporter can say that are a synonym of "it doesn't work". I hope this message does not come across as offensive, it's in no way meant as such. :D I do appreciate your contributions and you sharing thoughts about possible things that could be done and could be improved. However, I hope you understand that there's no way we can help when you use something else than the actual packages in Debian, do not provide any error messages seen, and describe what you see instead as "it felt like everything wanted to explode". For me, Xen 4.16 does run OK on my test servers, FWIW. Have fun, Hans
I'm aware I've got things in a state which is outside the support envelope. I was hoping observations might also apply inside the support envelope. That doesn't surprise me, it didn't take long to get things into a working state for me. Just I was able to get things into a problematic state which the packaging is supposed to prevent. xen-utils-4.16 depends on: libxencall1, libxenevtchn1, libxenforeignmemory1, libxengnttab1, and libxentoollog1. On a system being upgraded there will be 3 versions of each of these libraries available. 4.14.3+32-g9de3671772-1 4.14.3+32-g9de3671772-1~deb11u1 4.16.0-1~exp1 Issue is the rebuilt xen-hypervisor-4.16 and xen-utils-4.16 could be installed without updating libxencall1, libxenevtchn1, libxenforeignmemory1, libxengnttab1, and libxentoollog1. With the 4.14.3+32-g9de3671772-1~deb11u1 versions of libraries things were broken. I'm unsure which one(s) was the problem, though the problem disappeared once all 5 were updated. That enough for you?
