I'm setting up a few KVM virtual guests and I'm debating which disk type to use. I haven't been able to find a good resource online that runs down the pros and cons of each.
Can you help me create a list of the different disk type and the advantages and disadvantages of each? Here are the disk types I know about:
- Raw image
- Dedicated partition (eg, in LVM)
I'm curious about these criteria:
- Ease of setup (how easy is it to create each type)
- Ease of cloning
- Ease of expanding (to make bigger, so the virtual guest has more disk space)
- Features specific to that disk type
- Ease of backup
- Migration to other hosts
Can you help me evaluate my choices?
