I have confirmed that the same problem happens in virsh clients compiled for RHEL5 as well.

So far we have only been able to get virsh client-only compiled/installed to non-standard directory to an RHEL6 to connect to a working virtualization server.

Googling for the error message doesn't help much

A small correction, Clients build on RHEL 6 works fine, RHEL 4 doesn't work, we haven't tried the compilation on RHEL 5 yet.

Subject: QEMU+SSH login issue on RHEL 4

Hi All,

I am trying to compile libvirt tools from source on RHEL 4. I could get the sources compiled, but when I try to connect to libvirtd using QEMU+SSH I get the following error:

error: failed to connect to the hypervisor
error: authentication failed: unsupported authentication type 2
 
With root as the user, I could login, rest other users get the error. All authentication related settings are setup fine. When I try the login using QEMU+SSH to the same libvirtd, compiled on RHEL 5, with any other user things seem to be working fine. The thing that was different in the build is that I am trying to build a minimal virsh client on RHEL 4. The following are the configure parameters I used:

./configure --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



Are there any specific options that are needed for QEMU+SSH to work? any other ideas what could go wrong? 

Thanks,
Shantan
