Came across two bugs on a XenServer 7 deployment in combination with XenDesktop/XenApp 7.12 worth sharing:
The first is a mouse alignment issue which results in VNC mouse pointer slowness or disalignment of the pointer on a console session in XenServer, the following can check the status of the usb and usb_tablet parameters on the vm’s:
## xe vm-list uuid=[of the provisioned machine] params=platform
which will give the output of the VM and the following command will set the value’s:
## xe vm-param-set uuid=[of the provisioned machine] platform:usb=true
## xe vm-param-set uuid=[of the provisioned machine] platform:usb_tablet=true
confirm the settings with the xe vm-list command and afterwards reboot the machine and the issue is resolved.
The second bug is in a newly provisioned MCS catalog the XenTools of all provisioned machines won’t get installed, there is a private fix for this with Citrix Support under LC6769, the definitive solution shall be updated in 7.13 according to support.
