The following are pings from the VM which is ridiculously high.

Pings from the Hyper-V host is fine and normal.

Possible Solutions:

Microsoft recommends to use the “/usepmtimer” flag in the boot.ini of the respective guest OS in order to avoid similar issues.

Assign a single core CPU to the virtual machine.

Disalbe TCP offloading if enabled.
