The timeout does not seem to ever kick in and the DomU more or less sits there churning CPU waiting for a selection. Once a selection is made, we move to problem #2. 2) When the DomU boots, I see this as one of the last messages before the DomU kernel takes over: backend at /local/domain/0/backend/vfb/55/0 /local/domain/0/backend/vkbd/55/0 connected ************************** KBDFRONT Thread "kbdfront" exited. /local/domain/0/backend/vfb/55/0 connected ************************** FBFRONT Thread "kbdfront close": pointer: 0x2200004550, stack: 0x3a30000 close fb: backend at /local/domain/0/backend/vfb/55/0 close kbd: backend at /local/domain/0/backend/vkbd/55/0 Booting 'Scientific Linux (3.14.21-1.el6xen.x86_64)' At this point, the VNC server dies and never returns. No VNC connections are accepted at this point on - and the port (verified via netstat -lnp) is not open. I have tried this with both the following layouts of options: vfb =3D [ 'type=3Dvnc, vnclisten=3D192.168.1.1, vncpasswd=3Dsupasecret, vncdisplay=3D10' ] and; vnc =3D 1 vnclisten =3D "192.168.1.1" Has anyone had VNC working properly? # xl info host : xenhost.local release : 3.14.20-1.el6xen.x86_64 version : #1 SMP Mon Oct 6 22:03:42 EST 2014 machine : x86_64 nr_cpus : 8 max_cpu_id : 7 nr_nodes : 1 cores_per_socket : 4 threads_per_core : 1 cpu_mhz : 2327 hw_caps : bfebfbff:20000800:00000000:00000900:0004e3bd:00000000:00000001:00000000 virt_caps : hvm total_memory : 20479 free_memory : 2587 sharing_freed_memory : 0 sharing_used_memory : 0 outstanding_claims : 0 free_cpus : 0 xen_major : 4 xen_minor : 4 xen_extra : .1 xen_version : 4.4.1 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=3D0xffff800000000000 xen_changeset : xen_commandline : dom0_mem=3D1G cpufreq=3Dxen dom0_max_vcpus=3D1 dom0_vcpus_pin console=3Dtty0 console=3Dcom1 com1=3D115200,8n1 cc_compiler : gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4) cc_compile_by : mockbuild cc_compile_domain : crc.id.au cc_compile_date : Tue Oct 7 01:00:52 EST 2014 xend_config_format : 4 --=20 Steven Haigh Email: netwiz@crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 --OUkxbjJnp5oavc09HAeOXfqU6NgcC0904 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQIcBAEBAgAGBQJURnkIAAoJEEGvNdV6fTHcZfgP/0ce4LoFnlggg0Q8ivLTyd88 yy10elHiS5e5NYftomzwDsAUh2SjmjdIjV9tAmkbDh8P7OKvWz02rijTV9Xifgp3 f/NWCvYtVDQB+5I1GUI3sYqtoMxS/lvAbxt4l8/lduSP/OF+m03RQFnRd5GyfcjN BVbuVdtPz7kizmfTS4xAKgv1E781BlxOLI+MScl3GdsdbaW6FE7xl17UBF4oVw2H Gm0vla3QgkBJUO7Px5ZS0o5YSzr4fYUZDjS20DtF0s3LQ29+8S1DftEMXCJuCX5D kXvJboSyy+GMMTngH+11lJsJxudELDIMh/DMONJSB8deVE0pXyfrCSXVCy3ikIWT qz8YpHVrVKFhno5LWS/Dlwjf9BaoVwynaj3BtOlFjawLH2fPuTo+UTzTdzerzlB9 hJNlxusnhIEI2u8asL1LcwVMJPoxHNpMoh2Un1fSMrO/i+1SSdPoR2KIExFcDCA3 KbBWz/+dHBwjid/Z/xBQBKUDyukD1oEP4v8iI4Lk/yr40DkpRDsQ1EhXNHHQH/ua VuycH/Rsg9vAhDef6cQqPBAQl2Pq9s5rDnHVAccWKlkj8jYlybNIbsdEE8S37YNU ZTHvk8+frXbF9HCUIi3RYs+NRn8MhOXDzOj9SIgkO8OZowYPHnzKWBqT567izKzM jWcSEy81yWWz446vlizp =eXKX -----END PGP SIGNATURE----- --OUkxbjJnp5oavc09HAeOXfqU6NgcC0904-- --===============5661262370634857227== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel --===============5661262370634857227==--
