Hello Folks,
plain "xl list" produces:
> # xl list
> Name ID Mem VCPUs State Time(s)
> Domain-0 0 2048 1 r----- 108.2
and "xl list -l" produces:
> # xl list -l

why doesn't "xl list -l" provide the "State" information that the plain "xl
list" provides? I would have thought the JSON output would be complete.
cheers,

Hello Folks,
Sorry, forgot to mention the version:

plain "xl list" produces:

and "xl list -l" produces:
> # xl list -l

This is for Linux kernel, not Xen. To get Xen version:
xl info | egrep 'major|minor|extra'

Because for reasons I don't know the long output format is actually
printing out the domain configuration.
It wouldn't be too difficult to add a new option to generate JSON output
according to short output, but unfortunately I don't have time to work
on this at the moment.
