Eduardo, is the libvirtd daemon necessary for libvirt-based to manage the PowerVM node? I guess so, if it's the case, then what's the environment in the PowerVM-based node to run the libvirtd daemon, is it vios? Dennis,
libvirtd isn't necessary to manage LPARs. You just need to run virsh in your own computer in order to connect to an HMC/VIOS or IVM environment.
Any questions please feel free to ask.
Regards,
Eduardo,
Thanks for the help! I encounter an issue when trying to connect the remote VIOS/IVM server:
1. The used virsh is built from 0.9.12 source code with ./configure --prefix=/usr --with-phyp; make; make install;
2. When I try to connect the VIOS server with ssh, it succeeds with output looks like: root@dennis-:/home/libvirt-0.9.12# ssh padmin@10.30.56.60 padmin@172.30.56.60's password: Last unsuccessful login: Wed Jul 4 21:22:22 CDT 2012 on ssh from 10.16.10.94 Last login: Wed Jul 4 21:23:14 CDT 2012 on /dev/pts/1 from 10.16.10.94 [vios:/home/padmin]
3. My virsh runs in the local ubuntu 12.04 system, and I've executed the following command: sudo usermod -G libvirtd -a padmin
4. When I try connect the VIOS server with virsh, issue occurs:
root@dennis-:/home/libvirt-0.9.12# virsh -c phyp://padmin@10.30.56.60 Enter padmin's password for 10.30.56.60: error: An error occurred, but the cause is unknown error: failed to connect to the hypervisor
root@dennis-:/home/libvirt-0.9.12# virsh -c phyp+ssh://padmin@10.30.56.60 padmin@10.30.56.60's password: error: End of file while reading data: bash: sh: command not found: Input/output error error: failed to connect to the hypervisor
some times the last command also shows error message like: root@dennis-:/home/libvirt-0.9.12# virsh -c phyp+ssh://padmin@10.30.56.60 padmin@10.30.56.60's password: error: Cannot recv data: bash: sh: command not found: Connection reset by peer error: failed to connect to the hypervisor
Is there any tips about this?
Sorry for the late reply. You must connect to the HMC instead of the VIOS - VIOS commands will be transparently passed along the HMC tunnel. You also must specify the managed system name in the command line: $ virsh -c phyp://user@[hmc|ivm]/managed_system I'll try to post a patch this week to update the documentation. Any issues please feel free to ping me in the IRC as well. -- Eduardo Otubo Software Engineer Linux Technology Center IBM Systems & Technology Group Mobile: +55 19 8135 0885 eotubo@linux.vnet.ibm.com
