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
The command string for qemu will look like qemu -serial /dev/mydev ... But I would like to modify the libvirt definition XML file (in /etc/libvirt/qemu). Stefan notes in his blog (http://blog.vmsplice.net/2011/04/how-to-pass-qemu-command-line-options.html) that the options will look like:

Should I send questions to libvirt-users@redhat.com instead ? I would ask more questions.
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. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org On 05/28/2014 08:43 AM, Alexander Binun wrote:
