Re: [one-users] live-/migration not working, uknown error
Hey Carlos, thank you soo much for your help. By now I can finally migrate my machines normally. The only problem I, still having is the Live Migration! This is what the log says: n May 30 12:35:39 2011 [LCM][I]: New VM state is MIGRATE Mon May 30 12:35:40 2011 [VMM][I]: Command execution fail: 'if [ -x /var/tmp/one/vmm/kvm/migrate ]; then /var/tmp/one/vmm/kvm/migrate one-31 192.168.0.3; else exit 42; fi' Mon May 30 12:35:40 2011 [VMM][I]: STDERR follows.

Mon May 30 12:35:41 2011 [VMM][D]: Monitor Information: CPU : 18 Memory: 524288 Net_TX: 300 Net_RX: 1248 Is it possible that I somehow messed up the TLS encryption? I configured my cloud according to this website http://hpc.uamr.de/wissen/opennebula-workshop/ In one point on the website it says: For live migration and secured VNC, Transport Layer Security needs to be set up. A step by step guide can be found in the TLS Setup Guide of Libvirt. However, I didnt dothis part of the tutorial since I didnt find these steps in any of the other guides I was reading, including the official opennebula-guide. Is there something I missed? Do I have to perform this TLS Setup? A tiny bit of further help would be more than appreciated J Thanks in advance! Von: Carlos Martín Sánchez [mailto:cmar...@opennebula.org] Gesendet: Montag, 30.

Re: [one-users] live-/migration not working, uknown error
Hey, I already changed that part, and also performed a onehost sync afterwards, but still the unknown error issue appears. I wonder if I overlooked something else...although it's not possible, because I really read the tutorials thoroughly. Also, I checked the lists already - I check them every time before I post something new. I don't wanna end up spamming the whole list here! :) Thanks very much, for the help up to now! -Ursprüngliche Nachricht- Von: Steffen Neumann [mailto:sneum...@ipb-halle.de] Gesendet: Montag, 30.
