Re: [libvirt-users] libvirt logging of virDomainAttachDeviceFlags()
Hi,
Michel, you're right ; I got this error :
virDomainAttachDeviceFlags( ) error operation forbidden: read only access prevents
virDomainAttachDeviceFlags
Either via "virsh attach-device" or via "virDomainAttachDeviceFlags()"
, I encounter an error due to the fact that an authorized user is required.
Script-wise the error is the following :
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.)
I have now to add a user , following this ovirt people recommendation :
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 override that you need to create yourself a SASL user + password using the
saslpasswd2 command
Thx for help.
Regards,
J.P.

Hi,
When using « virsh attach-device ....." to add a channel device to a Guest , I
see following entry in libvirt log :
2015-12-07 11:14:47.307+0000: 14551: debug : virDomainAttachDeviceFlags:10433 :

Great !!
But , when calling virDomainAttachDeviceFlags( ) from a C program , I got return code -1
but nothing appears related to virDomainAttachDeviceFlags( ) in the libvirt log file .
Others libvirt calls of this C program are correctly logged .
Did I misunderstand something ?
This looks like the client has not even gotten into RPC call. This means that you are
passing a wrong argument somewhere. You can:
1) check here what arguments are being checked for:
http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/libvirt-domain.c;h=b91...
2) Use virGetLastError() to check the actual error.
