RE: [Xen-devel] I meet some problem when using stubdom, anybody could help? -:)

Hi, Samuel

Thanks a lot for your quick response.
I pull (18076)top of changeset today. Pull all needed .gz files such as lwip, 
zlib, newlib, bciutils, grub, etc. Do a clean compile/install. All succeed.

And then I used your sample config files (xmexample.hvm-stubdom, copy 
stubdom-ExampleHVMDomain to /etc/xen/),the only change I make is the disk file 
location. Yet I meet same problem two days ago (Yesterday I meet xend hang 
problem). See below:


[root@lke_linux examples]# /usr/sbin/fs-backend &
[1] 2930
[root@lke_linux examples]# Connection to the xenbus deamon opened successfully.
XS transaction is 5
xenbus_printf (backend/vfs/exports/0/name) <= default.
Path changed backend/vfs/exports/requests
Awaiting next connection.


The error is something like below:

[root@lke_linux configfile]# xm cr xmexample.hvm-stubdom 
Using config file "./xmexample.hvm-stubdom".
Error: ('b14ee2c2-d117-65fc-6338-2823a59ab5b8', 'VM_metrics')

So There's something I did wrong here? Thanks!

Regards,
Criping

Hum, odd...  Could you post the relevent parts of /var/log/xen files?
I guess you have upgraded your xen tools and hypervisor?

I haven't seen anything wrong.

The stubdom is created for each hvm domain by the stubdom-dm script,
i.e. only when you run xm cr -c hvmdom.hvm

I can do that indeed.
