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 dia=
log 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 cre=
ating 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 it=
s creation :
/var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qem=
u.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 wh=
ich forum is the right one for this kind of subject.
Thanks for help.
Regards,
J.P. Ribeauville

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 ?
When you attach a compute node to oVirt, it sets up auth with libvirt
to prevent admins from connecting to libvirt. If you want to oiverride
that you need to create yourself a SASL user + password using the
saslpasswd2 command eg see
http://libvirt.org/auth.html#ACL_server_username

Daniel

are you adding it later, when the VM is running? Is it a requirement to do it this way?
You can use oVirt vdsm hook[1] to inject custom snippet to libvirt’s xml on VM startup and
add any channel you want.
It would also allow you to pass arbitrary parameters from oVirt UI, should you ever need
them.
Thanks,
