This is what I see, not sure how that correlates to the correct tools build for 7.6

xe vm-param-get param-name=PV-drivers-version uuid=3a8a717f-c998-f05f-d096-f486a4990d1
major: 7; minor: 4; micro: 50; build: 1

Thx Will

I just upgraded from version 7.5 to 7.6 using yum upgrade, all seemed to go without error.
When I started to migrate our vm's from one of the 7.5 hosts to the new 7.6 host the vm's would be hung and unresponsive on the new host when the migration completed.
A forced stop and a fresh start of the VM brought the VMs back up.
After finding this post and seeing the notes about "xe-guest-utilities" I noticed that when I install the guest-tools the version remains the same, in fact the version remains at 7.4 looking at it in XCP-ng Center.
Optimized (version 7.4 installed)

This is what I see when I install guest-tools after migrating the VM to the 7.6 host.

What is the correct version of guest-tools?
Are guest-tools not being updated because I have used yum to upgrade for the last 2 versions?
I should note these are 95% Linux VM's

Thanks, Will
