VMware certainly these days performs really well especially with fast I/O and easy peripheral connections so for home users IMO that's the easiest way to get sensible VM performance and works straight OOB for most people. Fine for desktops etc and software testing.įor 24/7 operation type 1 is obviously the way to go - my problem is that any sort of VM I've tried running using HYPER-V runs like an absolute dog compared with KVM (mega fast but you do need a lot of expertise in Linux to set it up) or Esxi which is perfect for that type of job - the whole OS can boot easily from an internal SD card / USB drive if you don't mind a slightly longer boot than by having it from a hard disk -bog problem though for Esxi is that the boot device takes the WHOLE device and can't be run for a partition and that the remaining space can't be used for adding to the data store etc so inacessible for VM's etc. The trick is to have as small an OS as possible when using a type 2 VM software and in general you'll probably need a GUI (also overhead when running VM's) and with Windows (not the server editons) being a single user system means probably when that user logs off the VM software (and hence the VM's) aren't available. Using a Type 2 Hypervisor obviously has all to carry all the overhead of the HOST OS (running the software) and then use "paravirtualised" hardware etc - although some limited pass through e.g RAW HDD's allow use of the real hardware by the VM.
