Hello,
I am using Scientific Linux 5.4 and xen. I want to deploy a sample
ttyimage by creating a domain using virsh create.
My configuration file is :
-----------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<domain type='xen'>
<name>ttyimage</name>
<os>
<type>linux</type>
<kernel>/boot/vmlinuz-2.6.18-164.2.1.el5xen</kernel>
</os>
<memory>65536</memory>
<vcpu>1</vcpu>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<graphics type='vnc' port='5900'/>
<disk type='file'>
<source
file='/usr/local/ttylinux-xen-libvirt/ttylinux-xen.img' />
<target dev='sda' />
</disk>
<interface type='bridge'>
<source bridge='virbr0' />
<mac address='00:1d:60:ec:ae:1c' />
<target dev='testnimb-0' />
</interface>
</devices>
</domain>
-------------------------------------------------------------------------------------------------------
when I use "virsh -c "xen:///" create libvirt-ttylinux.xml " to
create a domain, the domain is crated and i can view the image (in
paused mode) using the virt-manager. and when I resume the image it
,disappears (domain gets destroyed) after nearly 10 seconds.....
Further when I use vncviewer localhost::5900 when the image is
running (during the 10 sec) ,i can view the console. But it closes
once the domain is destroyed.
Can someone explain why the image is not stable??? how can I make the
domain to be stable????
Thanks in advance

Using 'virsh create guest.xml' cmds can simply activate the guest, which
only exist active domain instead of define domain,
and the guest will disappear if it isn't in define domain and you carry
out some operations, e.g. 'destroy' or 'shutdown' or
'save' etc. so you should correctly use virsh cmds:
FYI,
virsh -c xen:/// define libvirt-ttylinux.xml
virsh start guestname
