I tried to follow the instructions in the FC6 Xen fedoraproject wiki page and tried installing 32 bit FC6 guest while booted in x86_64 dom0, the virt-manager tells me invalid argument and the xend-debug.log file says ERROR: Kernel not a Xen-compatible Elf image. Does this mean it is, in fact, impossible to run a 32bit guest (x86 architecture) on a 64 bit x86_64 host? Or does it just mean virt-manager isn't prepared to try doing an install from a 32 bit fedora install tree? Installing an x86_64 guest seems to be working fine, by the way. (I can't ever seem to find a plain statement about 32 versus 64 bit compatibility under Xen, though I have seen plain statements that I can't run a 64 bit guest under and 32 bit host, which sort of implies by omission that maybe I can run a 32 bit guest under a 64 bit host as long as we are talking x86 architecture in general). -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
No, this isn't a limitation of virt-manager; it's a limitation of Xen. The problem with a clear statement is that things are always moving :). As far as I know, it currently stands like this (where domU is paravirtualized domains and HVM is fully-virtualized domains): Hypervisor dom0 domU HVM ------------------------------------------------------------- 32-bit 32-bit 32-bit 32-bit 32-bit PAE 32-bit PAE 32-bit PAE 32-bit PAE 64-bit 64-bit 64-bit 32- or 64-bit There is ongoing work upstream to allow 32-bit domU's to run on 64-bit hypervisors, but that doesn't work right now.
