Why is it NULL instead of the path to pygrub? On Solaris, the path is
different.

Loader is refering specifically to the <loader> tag which is a BIOS
firmware blob. It seems we've not specified any tag in the capabilities
for bootloader info.

virt-install code seems to disagree:
elif self.boot_caps.loader == "pygrub" or (self.boot_caps.loader is None
and self.boot_caps.type == "xen"):
osblob += " </os>\n"
osblob += " <bootloader>/usr/bin/pygrub</bootloader>"
Now, if that's an error, that's fine. I have a patch on the way that fixes up
the pygrub path based upon caps.host.arch when available (as this is always
i86pc on Solaris).

Hard-coding it in libvirt would be fine (in much the same way you do for
emulator and HVM loader today). My patch to virt-install (hopefully)
fixes the code to actually query capabilities for these values, pygrub
excepted.

Yep, that virt-install code is wrong.

You mean that when dumping the capabilities on a Xen host
the sections
<guest>
<os_type>xen</os_type>
<arch ...
don't have a <loader> section under <arch> ?
The pygrub path is not provided by xen as far as i can tell, and not hardcoded
anywhere into libvirt it usually comes from the xen PV config files directly.
the Capabilities dump gets its informations from the kernel and hypervisor
(xend in that case), but the information is not provided there, are you
suggesting to check a few locations on the filesystem ?
