Xen vs KVM

Xen

https://wiki.xenproject.org/wiki/Compiling_Xen_From_Source

apt-get build-dep xen   # `deb-src` required
make xenconfig # kernel 4.2+

apt-get install xen-system

VSphere / ESXi

Raw disk mapping (RDM)

ls -alh /vmfs/devices/disks
vmkfstools -r /vmfs/devices/disks/<device> example.vmdk
vmkfstools -z /vmfs/devices/disks/<device> example.vmdk

Config

Backup

vim-cmd hostsvc/firmware/backup_config

Restore

vim-cmd hostsvc/maintenance_mode_enter
vim-cmd hostsvc/firmware/restore_config /tmp/configBundle.tgz

vmdk

vmkfstools -i "source.vmdk" -d thin "destination.vmdk"

The tool also reverts a vmdk which was blown up, back into a thin file! (Ref)

Intel vPro

https://en.wikipedia.org/wiki/Intel_vPro Intel vPro technology is an umbrella marketing term used by Intel for a large collection of computer hardware technologies, including Hyperthreading, Turbo Boost 3.0, VT-x, VT-d, Trusted Execution Technology (TXT), and Intel Active Management Technology (AMT).[1] When the vPro brand was launched (circa 2007), it was identified primarily with AMT,[2][3] thus some journalists still consider AMT to be the essence of vPro.[4]
