Re: [libvirt-users] caps->nguests == 0?

hi,
I compiled the libvirt-0.9.10 and started the libvirtd with sudo.
Unfortunately, I got an Error, saying 'virDomainDefParseXML unknown OS
type hvm'. I debugged it and found in function
virCapabilitiesSupportsGuestOSType, the parameter caps->nguests is 0.
On the other hand, I tried start the libvirtd with common user, and
creating domain with virsh, i found the caps->ngusts is 2 and had one
value 'hvm', so it didn't complain the error above, instead, it
complained could not load PC BIOS bios.bin.
I'd say I searched a lot and people say it's caused by without loading
kvm and kvm-intel module. So, I checked and it is loaded. Any tips
here?
Please check libvirtd.log further, if you saw the following similar error:
xxxx : xxxx : error : qemuCapsComputeCmdFlags:1209 : unsupported
configuration: this qemu binary requires libvirt to be compiled with yajl
xxxx : xxxx : error : virDomainDefParseXML:8312 : internal error No
guest options available for arch 'x86_64'
It means you need to install yajl-devel rpm package, for more, you may
run './configure -h':
# ./configure -h | grep yajl
--with-yajl use YAJL for JSON parsing/formatting
[default=check]
BTW, If you're compiling a current libvirt upstream, you will get a
friendly reminder, so suggest to try latest libvirt upstream.
