Hi,
I am in a process to virtualize an existing non-virtualized CentOS5 system.
Everything else works fine except X: virt-manager's console just hangs after bootup. I can use the text console though and what I see in X server's log is the error message "screens not found".
The only graphics related setup I've done is in the domu config this line:
vfb = [ "type=vnc,vncunused=1,keymap=fi" ]
Is there something else I should configure on the guest or in dom0?
Regards,
Peter

That should be enough. Is the xen-fbfront module loaded in the guest? Can you post the output of "xenstore-ls" after creating the domU?

Not is not:
"
# lsmod |grep xen
xennet 62409 0 [permanent]
xenblk 51497 2
"
I do not think on CentOS5 there is such module available? At least "modinfo xen-fbfront" does not find it.
If that is same as kernel option
CONFIG_XEN_FRAMEBUFFER=y then it should be compiled in the kernel?

Sure, you can find it here:
Little more info about my setup:
dom0 is setup on CentOS6 and has the following xen related packages installed:
[root@xen2 ~]# rpm -qa |grep xen
centos-release-xen-6-2.el6.centos.x86_64
xen-licenses-4.2.4-29.el6.centos.alt.x86_64
xen-runtime-4.2.4-29.el6.centos.alt.x86_64
libvirt-daemon-xen-0.10.2.8-6.el6.centos.alt.x86_64
xen-hypervisor-4.2.4-29.el6.centos.alt.x86_64
xen-libs-4.2.4-29.el6.centos.alt.x86_64
xen-4.2.4-29.el6.centos.alt.x86_64
libvirt-daemon-driver-xen-0.10.2.8-6.el6.centos.alt.x86_64
The goal I am trying to achieve is to replicate the following setup which works ok on a physical server: to be able to run X and issue xhost + as the tomcat user, so a web app running on the same server can access MapXtreme maps provided by Tomcat. I tried installing FreenNX server which did give me a working desktop session for the tomcat user, but issuing xhost + there did not help me (the webapp couldn't access the map service).
Best regards, Peter

Strangely enough according to xenstore, vfb is running and connected.
Can you try connecting to it using xm or vncviewer directly?
Or maybe setup the guest to use a simple fbcon just to try out if it works, and then setup the more complicated environment you are looking for afterwards?
