Just my blog

Blog about everything, mostly about tech stuff I made. Here is the list of stuff I'm using at my blog. Feel free to ask me about implementations.

Soft I recommend
Py lib I recommend

I'm using these libraries so you can ask me about them.

From vmdk to vhd

  • StarWind V2V Image Converter
  • VMware vCenter Converter Standalone Client

The conclusion after migration VMvsHyperV

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



  • The 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 a HUGE MGMT-VM to host vCenterServer because of the new VM ver. cannot be managed just from preinstalled vC-client.
  • Linux Vms such as Centos 6, Debian etc look good and running happily, the only change I've made - …


Get Acess to VMFS from Windows (Vmplayer+Centos6)

  • http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/

Above May not work. So make a VMplayer VM with ESXi installation and mound physical disk where VMFS present. http://www.empirion.co.uk/vmware/vmware-vsphere-client-direct-download-links/ This is the biggest technical perversion I've ever did: There are:VM-vs-MS_pervertion

  • VmWare
    • Vmplayer + ESXi
    • mounted IDE disks with VMFS
    • bridged network
    • vSphereClient
    • added datastores
    • added NFS datastore to host where vmplayer runs (thought it were faster then just download)
  • Windows Server 2012
    • NFS role and share
    • enought space

Bad method. Spent to much time. [su_box title="Warning IMHO!" box_color="#e4b7b7"]Send to the furnace all other ways to download vmdk from vmfs disks at EESXi, do it this way:[/su_box]

  • On the host where you installed Windows 2012 (for example) and where HDD with ESXI disks is mounted install one of this
    • Hyper-V role
    • vmware player

[su_note]I assume you're smart enought to not install OS on the same disk where ESXi host kept it's filesystem?[/su_note]

  • Then create new virtual machine …


vmdk madness!

When reading a lot of guides how better migrate from ESXi to Hyper-V I've saw some madness and then I become mad too. I decided to copy important VMs, which I don't want to break, on my laptop. YEAH! VMX-VMDK   Guess what? I bet when I'll migrate almost VMs to Hyper-V one last VM wouldn't convert and I will run it under the VMbox with bridged NIC from Windows Server with Hyper-V. I feel it would be exactly like that!


Virtualization matrix

Very useful, much informative, wow! vm-matrix   http://www.virtualizationmatrix.com/matrix.php?category_search=all&free_based=1


from VmWare to Windows Hyper-V

So! This time has come! I will switch my virtual enviroment from Vmware to Windows Server 2012 + Hyper-v. I'm tired because of ESXi leak of RAM and CPU and unaviability to check a lot of health statements of my tower. If you are interested in this, grab y'r popcorn and check my tag "VMvsHyperV" in blog to watch my struggle! Let the battle begins! VM-vs-MS   Useful stuff:

Virtual Machine Disks consolidation is needed

Do not forget to delete your old snapshots or you will suffer because of CONSOLIDATION! If you're made that mistake I made, there is solution: https://communities.vmware.com/message/2455176 http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2003638 FUCKING FUCK - I've spent 2hrs for this!

Consolidate virtual machine disk files


vSphere Datastore usage on disk - alert

Yo! Check this out and try to understand why this happens? Alerts saying there is less than 8Gb free on disk: diskusage160 Volume manager - says there is more than 55% free on that volume: diskusage160_REAL OMG WHY? - That is the question. P.S. - Inventory was reloaded, cleared, wiped. vCenter also has been re-installed totally and all SQL dbs was drop. This is the greatest secret of humanity, after reptiloids of course.
