This page seems centered around VBox for all aspects. It would be too much to duplicate for all KVM related instructions. Anyhow, the user base for KVM is already much more knowledgeable that such instructions would be overkill. Not out of elitism, but the install process itself is unfortunately a major filter for those who wouldn’t know how to set RAM to begin with.
That wiki page has been improved just now. It is now using a tab controller which makes it easy to switch the virtualizer which shows/hides the other virtualizer.
Shouldn’t be duplicated but would be good to shorten wiki/KVM by moving into the proper specialized wiki pages.
LVM is a disk partitioning tool, while spice is a graphics/media transfer protocol. There is a RAW disk mode in KVM where underlying disk storage is accessed directly without isolation, but the security consequences and data confidentiality violations are pretty evident.
Malware could recover deleted files from the host disk or inject malicious IO commands to the hardware.
Well i thought the vt-x is the issue, but i checked the BIOS and the vt-x is actually enabled, i also thought my PC is old and the vt-x is just not working anymore, but i tried another VMs in KVM and so as Virtualbox = working?!
So i think investigation need to be done, im happy to provide any further logs (my ticket is the first one).
