January 5, 20197 yr Is it possible to make a copy of a VM that I have and run it as a second VM?, I have this VM set up and is working flawless and would like to make a copy of it and run a second VM for other tasks. is this possible?
January 6, 20197 yr cp --reflink /path/to/vdisk.img /path/to/snapshot.img I use this method to have essentially 3 VMs running at the same time but not using 3 times as much space, since they are all identical windows VMs. Edited January 6, 20197 yr by bigwah
January 7, 20197 yr Author I get this when running command in Terminal root@Tower:~# cp --reflink /mnt/disks/Samsung_SSD_850_EVO_500GB_S3PTNB0J938117M/Win7-Distro/vdisk1.img /mnt/disks/Samsung_SSD_850_EVO_500GB_S3PTNB0J938117M/Win7-FTP/snapshot.img cp: failed to clone '/mnt/disks/Samsung_SSD_850_EVO_500GB_S3PTNB0J938117M/Win7-FTP/snapshot.img' from '/mnt/disks/Samsung_SSD_850_EVO_500GB_S3PTNB0J938117M/Win7-Distro/vdisk1.img': Operation not supported
January 7, 20197 yr I think cp --reflink can only be done of btrfs volumes. Is the operation taking place on a btrfs formatted drive?
