OK, i can reach the server, will update soon.

#2 Updated by Philippe May 6 months ago

The "gisaf.csr.av" virtual machine was not running, i started it manually and it's all fine.

It's supposed to start automatically, I'm checking to understand why it didn't.

Found in the log:

internal error: Failed to autostart VM 'gisaf2.csr.av': operation failed: Failed to balloon domain0 memory

I have some memory of such a message before. This kind of intermittent behavior during boot time, when a lot of activity is going on concurrently, is typical of a "race condition" (https://en.wikipedia.org/wiki/Race_condition).

Memory is currently only 8GB, and an upgrade to add 16GB is on the way. So, i'm closing the issue now as i expect memory management will be way less of an headache soon.
