[Xen-devel] current xen-unstable fails to xm start <name>
Hello,
current xen-unstable.hg-4.1.22019 fails to run ''xm start
<name>'', while
xen-unstable.hg-4.1.21976 was still ok.
Its not obvious from browsing the diff between the two trees whats the cause.
Any other info required besides the one pasted below?
# xm start $name
Error:
Usage: xm start <DomainName>

-p, --paused Do not unpause domain after starting it
-c, --console_autoconnect Connect to the console after the domain
is created
--vncviewer Connect to display via VNC after the
domain is created
--vncviewer-autopass Pass VNC password to viewer via stdin and
-autopass
/var/log/xen/xend.log shows this.

My guess would be that whatever writes cfg["vcpus_params"]["weight"] before the patched code is writing something other than an int and that this changeset means we no longer overwrite it with an int. I''m not familiar enough with xend to say where that original write is happening though.
