[libvirt-users] RHEL 5 libvirt client - QEMU+SSH fails with "unsupported authentication type 2" problem

[Saravanan Shanmugham (sarvi)]

After a bit more hacking through the code I think this has to do with PolicyKit authentication.

The server is currently enabled to do PolicyKit based authentication.
And policy kit is disabled or can't be found when building on RHEL4/5

Question:
    1. Is Policy Kit available  on RHEL4/5 and can  the libvirt client be policy kit enabled on the client?
    2. Without PolicyKit enabled on the client and server side, is it possible for a non-root user to have Read/Write "qemu:///system" remote access to the server?

Hi,
    I have RHEL5 libvirt client compiled at ${BSPACE}/usrcisco

This client when connecting to a libvirtd/server fails to connect as follows
-bash-3.2$ ${BSPACE}/usrcisco/bin/virsh -c qemu+ssh://sarvi@cnh-nehalem-1/system?socket=/var//run/libvirt/libvirt-sock
error: failed to connect to the hypervisor
error: authentication failed: unsupported authentication type 2

    I have the libvirt client compiled and installed as follows
PYTHON=${BSPACE}/usrcisco/bin/python LDFLAGS="-L${BSPACE}/libnl-1.1.2/lib/ -L${BSPACE}/device-mapper.1.02.28/lib/ioctl/" CFLAGS="-I${BSPACE}/libnl-1.1.2/include -I${BSPACE}/device-mapper.1.02.28/include/" CPPFLAGS="-I${BSPACE}/device-mapper.1.02.28/include/ -I${BSPACE}/libnl-1.1.2/include" ./configure --prefix=${BSPACE}/usrcisco --enable-static --with-libvirtd=no --with-hal=no --with-python --with-PACKAGE=yes --with-packager=no --with-packager-version=no --with-gnu-ld=no --with-apparmor=no --with-apparmor-mount=no--with-attr=no --with-audit=no --with-avahi=no --with-blkid=no --with-capng=no --with-curl=no --with-dbus=no --with-fuse=no --with-hal=no --with-netcf=no  --with-numactl=no  --with-openwsman=no  --with-pciaccess=no --with-sanlock=no  --with-sasl=no   --with-selinux=no  --with-selinux-mount=no  --with-udev=no   --with-yajl=no --with-xen=no  --with-xen-inotify=no  --with-qemu=no --with-uml=no --with-openvz=no--with-vmware=no --with-phyp=no --with-xenapi=no --with-libxl=no --with-vbox=no --with-gnutls=no --without-ssh2 --with-rhel5-api=yes

The same library sources when compiled on RHEL6 as above, without specifying the "--with-rhel5-api=yes" compiles AND connect to the same server fine

I am looking for pointers as to what the problem could be OR how to trouble shoot the problem.

Thanks,
Sarvi
