[bitfolk] You will need to be running in PVH mode to upgrade to Ubuntu 22.04.x

Hi, Since the first point release of Ubuntu 22.04 has now been and gone, those of you with older Ubuntu installations will now be prompted with suggestions to upgrade to it. That should go fine, as long as you are running 64-bit (amd64) and in PVH mode. If you aren't then it won't be able to boot, as the Ubuntu kernel uses a compression method not known to our PV mode bootloader. To switch to PVH mode you should do this from the Xen Shell: xen shell> virtmode pvh It will then take effect from the next boot. If it somehow doesn't work for you, you can switch back: xen shell> virtmode pv (and then please let us know so we can investigate) PVH mode has been the default for all new VMs here for two years now, but many existing customers are still running in PV mode. There's more information about PVH mode here, but really it is an implementation detail that you don't need to pay any attention to: https://tools.bitfolk.com/wiki/PVH Those running 32-bit Ubuntu have no upgrade path at all since 18.04 was the last Ubuntu release that supported 32-bit. Those wanting to upgrade from 32-bit Ubuntu 18.04 are probably going to be best off asking for a new VM to run for free for two weeks, and move their stuff into that: https://tools.bitfolk.com/wiki/Migrating_to_a_new_VPS Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
