viprion guest IMG, move from on host to another

hi

 

in theory, one could move a guest image from Viprion device to another (or maybe even another vCMP platform). Anyone tried that? Any caveats or stuff to pay attention too? I'm thinking of the license (each guest has a bigip.license file, derived from its host license) and the pre-requisite that the same VLANs (names) should exists on source and target platform.

 

Regards

    It is, in my experience, not any different than KVM. Licensing is handled on the chassis. As long as the licensing is the same on the new host, all should be good. I have just migrated from 2100 blades to 2150 blades. I did not save the images, I created new ones (mostly 'cause I moved interfaces around). I just used the UCS from the original guest to recover. When I created the new guest, I grabbed the VLAN tag as it was different from what was on the original guest. Once I applied the UCS, I just had to modify the vlan tags to match the new config. Was pretty simple.

     

    I have also recovered guests when the chassis config got blown away. The guest images where still there so I just recreated the guest in the VCMP host and it also recovered nicely so my guess is you won't have any issue. If your vlan names are changing, that might be more challenging, though a UCS is really just a tgz. You could untar it and make the appropriate config changes and retar it before applying.
