Prevent creation of vmmem files in VMware (Windows)

Issue

VMWare creates .vmem files to back the guest RAM. On the host this causes disk thrashing especially during powering on and off the guest.

Solution

Add the following lines to the .vmx file to prevent creation of .vmem files. This will reduce disk IO and VM performance will improve especially on non-SSD disks.

Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

• The virtual network device that is provided to the guest (e.g. a PCI network card).
• The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network

This writeup describes the process to fix Windows not booting on a VirtIO disk. The VPS only boots when changing the "Disk Driver" to IDE on SolusVM. When the disk device is VirtIO windows fails to boot with an INACCESSIBLE_BOOT_DEVICE error.

The issue was likely caused due to installation of OSFMount software previously.

Creating a full disk image

Before starting, a full disk image of the VPS may be taken for safety. Enable rescue mode in SolusVM. It will then display the SSH connection credentials. Connect to the server using the same credentials from another server which has sufficient disk space to store the full disk image. Run lsblk to list the disk drives attached to the system. To inspect the disk manually, run mount in readonly mode as shown.

# mount -o ro /dev/vda1 /mnt
