[Xen-users] Xendomains always broken for me, nobody else? Attempt 2

[Ian Murray <murrayie@xxxxxxxxxxx>]

Sorry for resending this but I am keen for a response either way and nobody did.

Thanks,

Ian.

Hi All,


Everytime I upgrade to a new version of Xen (just did 4.2.1 this weekend) I 
find the xendomains script completely unusable. I use xl exclusively and the 
behaviour is slightly different to what the script appears to be expecting.


Am I the only one that has this problem? I have an Ubuntu 12.04 based Xen 
server and a Scientific Linux 6.3 based server and both suffer the same problem.



I am no bash guru, so apologies if there are better/cleaner ways. I did submit 
it as a patch on the devel list but it got ignored plus I have no idea if it 
works for xm or not.



Thanks for reading,


Ian.
