Dear Friends,
I would ask you a question ; grateful in advance!
I have a program running on a VM guest. Its output is valuable (for VM
introspection) so I want to let the host module know about it. I prefer to
redirect ' stdio" of a guest into a device at the host (a text file or my
device that has the name "mydev"
and the driver is written for it).
I have the XML definition file for my VM in /etc/libvirt/qemu. I have added the
section:
<serial type="file">
<source path="/var/log/vm/vml.log"/>
<target port="0"/>
</serial>
into the /devices section.
That is I want the stdio to be streamed into the file /var/log/vm/vml.log at
the host.
Then I run simple textual commands at the guest (ls, pwd and so on). But I do
not see /var/log/vm/vml.log created at the host.
Please help me.
Thanks in advance,
Alexander Binun

No need to apologize - these lists exist to help people, and we were all
new once.

Yes, if your questions are related to libvirt, then asking on a libvirt
list will get you a better audience that may have better answers to your
questions.
