I want to give my clients access to their Xen domU consoles using VNC. This works great using vfb device configured as type=vnc. However I have 2 problems: * I can't figure out how I can add a vfb device to a running domain without restarting it (I have 100+ domU's I want to enable this on, and want to avoid restarting them all if possible) * Related, I can't figure out how I can change the VNC password without restarting the domU, as the password is specified in the vfb config. Is what I am trying to do possible? How? In case it matters: # xm info host : <my.supersecret.hostname> release : 2.6.18-194.26.1.el5xen version : #1 SMP Tue Nov 9 13:35:30 EST 2010 machine : x86_64 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 1 cores_per_socket : 4 threads_per_core : 1 cpu_mhz : 2394 hw_caps : bfebfbff:28100800:00000000:00000140:0098e3fd:00000000:00000001 total_memory : 24566 free_memory : 8317 node_to_cpu : node0:0-3 xen_major : 3 xen_minor : 1 xen_extra : .2-194.26.1.el5 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_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable cc_compiler : gcc version 4.1.2 20080704 (Red Hat 4.1.2-48) cc_compile_by : mockbuild cc_compile_domain : centos.org cc_compile_date : Tue Nov 9 12:45:24 EST 2010 xend_config_format : 2 Thanks in advance -- Chris Wik Anu Internet Services Ltd
