This example output is done for 2 guests, rhel5-32pv and rhel5-64fv, that are both running on the host and also we need to create the invalid file. Touch command is good enough to create the invalid save file so here's the output including the commands used: # touch /var/lib/xen/save/invalid; /etc/init.d/xendomains start Restoring Xen domains: invalid FAILED: Invalid restore image /var/lib/xen/save/invalid Restore image has been renamed to /var/lib/xen/save/.invalid An error occured while restoring domain invalid: Error: Restore failed ! Going on... Restoring domain rhel5-32pv Domain rhel5-32pv restored successfully rhel5-64fv Domain rhel5-64fv restored successfully . # Is that good? What do you think? Thanks, Michal Hi Michal, I think the improved output show more clear information and enough for the enhancement. Created attachment 483122 [details]
Improve xendomains output
Hi,
this is the patch for to implement a better xendomains script output.
It's been tested on RHEL-5 x86_64 dom0 with the patch applied and the
formatting seems to be a little better and not that much confused now.
Also, the output has been reviewed by Qixiang Wan <qwan> and
according to Qixiang the output is improved and the information output
are more clear now.
Michal
Fix built into xen-3.0.3-126.el5 verified the output has been improved with xen-3.0.3-129.el5. $ /etc/init.d/xendomains start Restoring Xen domains: invalid FAILED: Invalid restore image /var/lib/xen/save/invalid Restore image has been renamed to /var/lib/xen/save/.invalid An error occured while restoring domain invalid: Error: Restore failed! [failed] [FAILED]

Description of problem: The output message is a little confused when starting xendomains with invalid image and regular saved domain.

The "!" stands alone. Whether the "[failed]" shows the regular domain rhel5u5-32-pv restore failure or this "start xendomains service" operation failure? ......
