xsContainer failure to communicating with the plugin Hypervisor 8.2

[Riccardo Bicelli]

Hello,

after updating from 8.0 to 8.2 I have encountered an issue with container plugin. When creating coreOS VM or editing existing the provisioning doesn't work anymore.

The error in Xencenter says:

"There was a failure communicating with the plugin"

 

The xscontainer.log says:

Container plugin version is 1.0.4.

 

Looks like  the python module can't find the xs-tools.iso and throws an exception.

 

I see in the changelog of Hypervisor 8.2 that xs-tools.iso is no longer provided.

 

I opened a support case, but I'm also  looking to a (hopefully) temporary workaround.

the xs-container supp-pack no longer works with current Linux distributions and as a result support for this supplemental pack has been withdrawn.

hello,

 

Is this a single host or pool?

 

make sure the plugin/supplemental pack is installed on all hosts of the pool, if you are not sure, i recommend you manually install it again, downloading the latest version from the Citrix downloads page.

 

then try again 

[Riccardo Bicelli]

This is a pool and supplemental pack is installed on every host.

I downloaded from Citrix the latest version, tried to reinstall, but xe told me that I'm already on the latest version of the plugin.

So, uninstall supplemental pack and find another method for managing containers?
