Hi,

i'm new Citrix user.  I have a issue on  Windows 10 VM. Previusly i had try to modify the ammount of used ram on VM and changed the core numbers used in VM from 2 to 4.Once restarted, the VM is no longer booted. I have marked the problem in red. I can't start the VM anymore. Thank's for your help.

That should just be a message letting you know that you can't set a range until you install the XenTools (Management Agent). 

I think your VM isn't starting for another reason.

Previously xentools was already installed and worked. Now i cant poweron the vm for unknown reason. I've created a new VM and booted correctly. So i think something was corrupted in the vm. Fortunately it was a testing vm and not production vm.

Yea, you are having trouble with the vdi. Sometimes you can just detach/attach the disk and fix it, sometimes you can do a full copy

and get around that error as well.  \var\log\sr.log might give you more info as to what his happening.  If neither of those work a 

host restart might be something else to try.
