Hi, everyone:

When I install a vm on centos5.5, I got xen crashed:

Code:
 
# virt-install -n centos5 -r 512 --vcpus=1 --disk path=/home/mycoy/centos5.img,size=8 --nographics -l http://mirror01.idc.hinet.net/CentOS/5.5/isos/i386/CentOS-5.5-i386-netinstall.iso

when the above virt-install is executed, the download process began and there was no error. when the download finished, xen crashed immediately, and I got lots of following info:

VIRT-VIEWER(1)						User Contributed Perl Documentation					    VIRT-VIEWER(1)

NAME
virt-viewer - display the graphical console for a virtual machine SYNOPSIS
virt-viewer [OPTIONS] DOMAIN-NAME|ID|UUID DESCRIPTION
virt-viewer is a minimal tool for displaying the graphical console of a virtual machine. The console is accessed using the VNC protocol. The guest can be referred to based on its name, ID, or UUID. If the guest is not already running, then the viewer can be told to wait until is starts before attempting to connect to the console The viewer can connect to remote hosts to lookup the console information and then also connect to the remote console using the same network transport. OPTIONS
The following options are accepted when running "virt-viewer": -h, --help Display command line help summary -V, --version Display program version number -v, --verbose Display information about the connection -c URI, --connect=URI Specify the hypervisor connection URI -w, --wait Wait for the domain to start up before attempting to connect to the console -w, --reconnect Automatically reconnect to the domain if it shuts down and restarts -d, --direct Do not attempt to tunnel the console over SSH, even if the main connection URI used SSH. EXAMPLES
To connect to the guest called 'demo' running under Xen virt-viewer demo To connect to the guest with ID 7 running under QEMU virt-viewer --connect qemu:///system 7 To wait for the guest with UUID 66ab33c0-6919-a3f7-e659-16c82d248521 to startup and then connect, also reconnecting upon restart of VM virt-viewer --reconnect --wait 66ab33c0-6919-a3f7-e659-16c82d248521 To connect to a remote console using TLS virt-viewer --connect xen://example.org/ demo To connect to a remote host using SSH, lookup the guest config and then make a direct non-tunnelled connection of the console virt-viewer --direct --connect xen+ssh://root@example.org/ demo AUTHOR
