Re: [libvirt] Domain not stable while created...
Thanks Mr.Stefan I was getting some errors when i ran like xm create libvirt-ttylinux.conf Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory So this time as sure that there is some problem with my configuration file. I googled , then I found some solution to change the ramdisk option by some command mentioned in the following link. http://www.virtuatopia.com/index.php/A_Xen_Guest_OS_fails_to_boot_with_a_%22switchroot:_mount_failed:_No_such_file_or_directory_error_message%22_error_message. But after doing this when I restart my process by xm create... and virsh console... , I get -- Creating root device.

Hello,

I created a domain using virsh -c xen:/// define libvirt-ttylinux.xml
and
virsh start ttyimage for a simple ttyimage.
Problem I face is that the image shutsdown immedialtely once virsh
start guest is typed.

Will that crash mainly be due to the kernel ? Since am not sure

When I use via a config file using xm create libvirt-ttylinux.conf
, then the domain runs stable
But when I use the virsh -c xen:/// define libvirt-ttylinux.xml and

Maybe try to give it some more memory...
Otherwise I can just guess as to why there is such a difference in this vm
running stable. Are there any significant difference
between an 'xm list' after the 'xm create' and an 'xm list' after the
'virsh -c ... define'? Did you ever try 'xm new vm config file name'
followed
by an 'xm start domainname'?

Why is this difference between the xm (when i destroy the

while destroying the image) .
xm new vm definition filename - xm start domainname - xm destroy
domainname - xm delete domainname
is similar to
virsh ... define - virsh start domainname - virsh destroy
domainname - virsh undefine domainname

[libvirt] Domain not stable while created...
Hello Thanks for the reply. Now I use virsh -c xen:/// define libvirt-ttylinux.xml (domain is created) and virsh start ttyimage the image starts and shuts down immediately. This time I can view the domain even after the shut down. So is there any reason for the image being shutdown immediately? What else should I check?? Thanks in advance.
