The conclusion after migration VMvsHyperV


So, what can I say before migration. First day looks good, nothing leaks, all services works as expected, have some additional configuration for MAC addresses etc. During migration I’ve accidentally lost one system disk for one of my VM and photos backup disk, but this is not an issue, because all important stuff have more then one backup.

  • First expression about Hyper-V – it’s more thrifty to system resources, I’m still tuning it to make my vms run smoothly but this is the first thing I saw.
  • Then, Hyper-V has a good mgmt console for all my needs, I have a small env. so I do not need an HUGE MGMT-VM to host vCenterServer because new VM ver. cannot be managed just from preinstalled vC-client.
  • Linux Vms such as Centos 6, Debian etc looks good and running happy, only one change I’ve done – is bringing up eth0 again, because it was down (network hrdware changes)
  • The BIG plus to hyper-v for small env – can use all resources till vms are powered off! This is very important to make backups and convert virtual disks, file systems, etc.
It was so useful, when I have a different powerful tower PC to run all my vm conversion – from vmdk to vhd, and run disk defrag. etc. And if you have one hardware server for all your needs this is exactly all you need, you can have a powerful, running machine, which can use all RAM and CPU for all your migration, backup or other need. When I used ESXi, I can’t run mgmt tasks till all my vms are powered down, also I must keep my vCenterSever on another PC and keep it connected to ESXi host in any way.
  • Can mount all VHD – this is can be useful to manage broken vm or keep data if virtual host is down or broken. This can be very useful when you’re running some test machines which can be broken in some way.
  • Have visible and transparent system resources distribution.
This can be appealed by BIG guys from BIG data centers, which can say that vCenter has a better distribution bla-bla.. But I’ve see what is going on in my system, those shitty pools can’t keep crazy machines in their’s stall! When one of them, those tst crazy vm, starting to eat resources – nothing can stop it, and ESXi hangs, and this ESXI also can eat lot of them (resources).

This is the first expressions from Hyper-V, they may differs from yours and I also can change them during time. but the first expression still better then disappointment. Will see.
