Alex,
I've done make uninstall, rpm -e libvirt --nodeps and rpm -e libvirt-client
--nodeps before I rebuild ( ./autogen.sh --system && make && make install)
the libvirt.
It seems that the previous error has gone but warning is left:
[root at XenTester su]# libvirtd start
2012-03-16 14:37:04.511+0000: 29843: info : libvirt version: 0.9.10
2012-03-16 14:37:04.511+0000: 29843: warning : virGetHostname:2108 :
getaddrinfo failed for 'XenTester': Name or service not known
Does this warning really matter? Are there anything returned by getaddrinfo
will be used by guest OS?
Besides, could you please confirm if the following running script suggest
that Xen and libvirtd have been successfully connected?
[root at XenTester libvirt-0.9.10]# virt-install -p
ERROR
--name is required
--ram amount in MB is required
--disk storage must be specified (override with --nodisks)
