[ovirt-users] Spice in 4.0

[Ivan Bulatović]

‎To be able to use the .vv file, virt-viewer 2.0-8 is required and it can't be found in CentOS 7 repos. CentOS 6 repos contain 2.0-14 version however. Any info about when will the required version land in the CentOS 7 repositories?

TIA,

Ivan

Thank you Alex for jumping in
Additional note - the 4.0 distribution of spice components does not contain the XPI/ActiveX anymore, so in case you want to use the deprecated way you need to make sure you install the latest 3.6 version of ActiveX/XPI from 3.6 channels/repos

Melissa, may I ask what is the thin client you use? Does the vendor have a plan for future? Another non-intrusive option is to use the web-based console clients….which are of varying quality though, so not a feasible replacement in many cases.

Thanks,
michal
