Guest VM hangs

Guest VM hangs

Hi
When I write something from the dom0 into the
/local/domain/<domid>/memory/target using xenstore-write, the respective
<domid> guest VM hangs.
What is the reason for this? How to rectify?
And how to set the permissions in the domU. I am not able to do
xenstore-write at the shell. It returns an error saying could not write to
path.
Kindly help.

Hi,

I haven't tried modifying the guest target memory in xenstore directly
before, have you tried using xm mem-set to see if it still hangs? Maybe
there is more involved than just setting the target? I know that xm mem-max
is also required so chances you may need to set some max value elsewhere in
xenstore also..

In terms of writing from the guest you will need to use xenstore-chmod or
the C api to modify the permissions first.

I suggest reading the XenBus article on the wiki:
