**NOTE*** I've found solution.. Before i've used Citrix (XENSERVER) and the scheme of virtualization there was bit different. So that's why i'm stuck on some easy steps.. Well, the problem was that i'm using 61GB HDD, 5,5 GB of Memory. When i've create VM i''ve used maximum size of HDD and didn't left any space for SWAP file. I've used 58 GB, and you've to assume + size of your memory it means, 58 GB + 5,5 GB.. So that's why i didn't had enough space. Hope someone will find it helpful. Cheers,
