Hi, I tried to create a VM in ESXi 5.5 and to assign the interface to a Distributed switch portgroup. But i failed to achieve it. When i define a VM with distributed portgroup , i cannot see that distributed portgroup getting assigned to the VM network interface. My libvirt version is 0.10.2 I wish to know whether the libvirt supports assigning interface to a distributed port group ? If so how to proceed with it. Thanks, Vivek

Thanks for your help. My teacher advised me to use the "load_kld cpufreq" command and it resolved the problem. Tomasz Kowal

[libvirt-users] Libvirt Python Bindings - Remote Connection using openAuth.
by Sijo Jose 06 Jun '14

06 Jun '14

Hi, I am using libvirt with python binding, and I want to connect to a remote host. I was able to connect after making ssh certificate, but It is not applicable for my project. So I want to use openAuth() method, but I could not succeed connecting to a remote host using it. Here is my code ------------------------ import libvirt USER = "root" PASS = "mypasswd" def authcb(credentials, user_data): for credential in credentials: if credential[0] == libvirt.VIR_CRED_AUTHNAME: credential[4] = USER elif credential[0] == libvirt.VIR_CRED_PASSPHRASE: credential[4] = PASS return 0 auth = [[libvirt.VIR_CRED_AUTHNAME, libvirt.VIR_CRED_PASSPHRASE], authcb, None] conn = libvirt.openAuth("qemu+ssh://192.168.1.21/system", auth, 0) print conn.getHostname() ------------------------------- *If there is something wrong, how am I supposed to use it.* If its not the right place to get libvirt-python related help, from where can I get it. Regards Sijo

[libvirt-users] Updating domain XML issue
by Brian Rak 05 Jun '14

05 Jun '14

I'm trying to unmount a guest cdrom using libvirt_domain_update_device (via php-libvirt). The guest cdrom is currently mounted via Ceph, via this XML: <disk type='network' device='cdrom'> <driver name='qemu' type='raw'/> <auth username='cdroms'> <secret type='ceph' uuid='XXXX'/> </auth> <source protocol='rbd' name='cdrom/test'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> In order to unmount it, I'm trying to use this XML: <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> <alias name='ide0-1-0'/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> However, I'm getting an error from libvirt: 'internal error: invalid secret type 'ceph''. I suspect this is because it's still trying to use the authentication information from the old cdrom definition. How do I convince it to not do this? I've tried specifiying an empty <auth/> block, but that generates it's own error ('missing username for auth')
