Help! My VM randomly suspends!

  • Esnure your VM has actual RAM size defined accordingly  ([RAMSIZE] x 1024): (ex: 4096/8192) - RECOMMENDED 16GB (16384MB) minimum!
  • Set processor type to "host" on Proxmox VM

Increase the hard drive space of a PROXMOX VM:

  1. Shut down the VM
  2. Run the command: (Example: qm resize 100 ide0 +150G)
  3. qm resize [VM_ID] [DISK_NAME] +[SIZE_INCREASE]G
  4. Start the VM
  5. Go into Disk Management, right-click the drive you want to add the additional storage to and press extend volume
  6. As a general rule. Windows only allows you to extend partitions that are next to each other. If you your new unallocated volume is NOT physically next to your main partition, you will have to use a third party tool to "move" it next to it. I recommend > https://www.diskpart.com/download-home.html < The free version of this software has a solid and tested feature to re-arrange partitions on a physical drive. After using this tool to move your partition structure, you should now be able to complete 5.
  7. Send it.
  • In order to decrease the size of your VM volume, do these steps in reverse.
    • Shrink the volume in windows
    • Write down the amount of space you shrunk the volume by in G
    • qm resize [VM_ID] [DISK_NAME] -[SIZE_INCREASE]G
