The create wizard in virt-manager does not allow the user to choose the arch for a FV guest. I checked the 5.1 packages and this is NOT a regression, and since no one has reported it for a few release cycles, it doesn't seem to be too big of a deal. virt-manager-0.5.3-7.el5
How does one actually run FV from a pure RHEL5 install? I was about to file a bug to get it the FV disabled by default, but maybe I am missing something - I was assuming that is why the arch selector is empty?
Choosing arch is non-sensical for Xen fullvirt. It only supports 1 arch, which is that of the host machine. The arch selection UI is there for other non-Xen libvir drivers such as QEMU.
What about 32 on 64? Is that just for paravirt? I know it's not officially supported anyways but if it ever becomes official we should consider allowing it in virt-manager.
The arch drop down is refering to the architecture of the 'domain', which may or may not be the same as the architecture of the guest OS. ie, a 32-bit guest OS can run in a 64-bit domain. Xen HVM is emulating a 64-bit domain, that can run 32 or 64 bit OS. So there's no need to select a different arch for a 32-bit guest OS on a 64-bit host
ah I see. that's certainly a bit confusing. i'll close this bug if there are no objections.
So how about hiding the arch selector and kvm box when they are not relevant?
I'd rather not hide UI pieces, it just creates an inconsistent experience between hypervisors. Same could be said for disabling UI, but its more of a "Oh this is explicitly disabled, must not apply here" vs. "where the heck did that checkbox go?" Anyways, the original bug was NOTABUG, so closing
