Description of problem: virt-install writes vncdisplay=<vncport> in domain config when it should be <vncport - 5900>. Version-Release number of selected component (if applicable): libvirt 0.2.3-8.el5 xen-3.0.3-36.el5 xen-libs-3.0.3-36.el5 python-virtinst-0.103.0-3.el5 How reproducible: Always Steps to Reproduce: Run # virt-install --vnc --vncport=5920 --name=it128941 --vcpus=2 --ram=512 --file=/home/guests/it128941 --paravirt --location=http://172.32.0.1/rhel5/disc1 and check domain config: vfb = [ "type=vnc,vncdisplay=5920" ] Actual results: vfb = [ "type=vnc,vncdisplay=5920" ] Expected results: vfb = [ "type=vnc,vncdisplay=20" ] Code does: src/xm_internal.c:1975 ... } else { strcat(val, ",vncdisplay="); strcat(val, (const char*)vncport); ... it should do vncport - 5900. Patch attached.

Okay, assuming the problem is confirmed (I didn't checked yet) why is this of priority 'high' and 'urgent' ? Xen in 5.1 usually keep the definitions of domains in a separate database, and that's what is used when actually starting the domain or working with it. Please explain the kind of problem it raised in practice, Daniel
According with customer it works on RHEL5.0GA and fails on RHEL5.1 and they need this fixed otherwise it's impossible to keep track of vncports/vncdisplay.
Here is the reason why I escalated this issue as regression from EL5.0. ----------------------------------------- > If this doesn't occur on EL5.0GA, I can push this issue for 5.1 as the regression. This issue does not occur on RHEL5.0GA because the configuration file is made by the virt-install command. At RH5.1, that is made by libvirt. So could you push this issue ?

Problem reproduced, path fixes it: [root@paphio ~]# virsh dumpxml test254188 | grep vnc <graphics type='vnc' port='5920'/> [root@paphio ~]# grep vnc /etc/xen/test254188 vfb = [ "type=vnc,vncdisplay=20" ] [root@paphio ~]# rpm -q libvirt python-virtinst xen libvirt-0.2.3-9 python-virtinst-0.103.0-3.el5 xen-3.0.3-36.el5 [root@paphio ~]# Daniel
built libvirt-0.2.3-9.el5 in dist-5E-qu-candidate with the fix, Daniel
