/usr/local/bin? Are you sure this is the pygrub you built and installed
just now and not some other cruft?

Are you able to identify when it last worked and run a bisect? You don't
need to do a full boot of the guest, just run pygrub manually at each
stage.

I think this is just a warning (which needs to be toned down), since the
pvgrub kernel isn't a bzImage, it's a simple elf file.

Your logs show it building a Mini-OS domain, not an HVM one:
        domainbuilder: detail: xc_dom_find_loader: trying ELF-generic loader ...

        xc: detail:     virt_kstart      = 0x0
        xc: detail:     virt_kend        = 0x99ef00
        xc: detail:     virt_entry       = 0x0
        xc: detail:     p2m_base         = 0xffffffffffffffff
        
I think if you investigate more closely you would find it is working, at
least as far as building an running something..
