I also get a problem specific to host 2.6.16 kernels, but that's when I run x64 guests on x64 2.6.16 hosts (x86 32-bit guests work normally); I've not tested 32-bit 2.6.16 hosts. The error message is different. However, I can't exclude there is the same root cause acting in a different way, but I've now debugged this a bit and this seems unlikely. EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Warning: unable to open an initial console.
