Hi,

AFA IUnderstand , /var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0 is a channel used for QEMU agent , so no way to use it for private purpose.

no, it’s occupied by qemu-ga even if you don’t start the guest process occupying it you would likely be interfering with libvirt’s internal functionality…..create your own and you can do whatever you want:)

Hi,

I wrote a C program running in a KVM host. Part of it adds a Unix Channel device in all Guests in order to have a dialog from Host to Guest. As long as my host wasn't part of an Ovirt cluster , all was running fine.

I added my host in a ovirt cluster , and then , when running the script creating the channel device ( by using "virsh attach-device --persistent -live ....." ) , I got following error :

Please enter your authentication name: Please enter your password: error: failed to connect to the hypervisor error: no valid connection error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): generic failure: All-whitespace username.)

What's the user/password I've to use then ?

BTW , I've seen that following channel device was added to the Guest at its creation :

/var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0

What's used for ? I presume I cannot use for my private purpose ?

I sent this topic to ovirt and libvirt mailing lists , cos I don't know which forum is the right one for this kind of subject.

Thanks for help.

Regards,

J.P. Ribeauville
