Nevertheless i was able to access graphics using vnc. Even specifying vnc it tries to open display (maybe something requires it - virt-viewer). [root@localhost ~]# virt-install -n test -r 512 --vnc --file=/dev/VolGroup00/test-os --location=ftp://mirrors/centos/5/os/i386 -x 'text' --vncport=5900 Starting install...

You can reconnect to the console to complete the installation process. I access the console using vnc but as you said, after the instalation completes it didn't restart. It disappeared from "virsh list" but i'm able to start it again using: [root@localhost ~]# virsh start test Domain test started [root@localhost ~]# virsh list Id Name State ---------------------------------- 0 Domain-0 running 3 test idle If there's anything i can do to help please let me know.
