Well, your post is a little bit too condensed for me, so, could you provide 1) a VBox.log where you have observed the problem and 2) the <VMName>.vbox? Both of them zipped please...

socratis & perryg,
I've got these 3 files - vbox.log/best.vbox/hostonlyifs.txt, zipped into vbox.zip and attached for your review.
Thank you both for help.

You have two host only adapters and they are both wrong. Delete the number two host only adapter ( look in preference -> network )
Edit the first one to equal the two screenshots provided. ( see below )
Next your Extension pack does not match the running version of VirtualBox.

Perryg,
Deleted HostOnly #2, edited #3 following you.
Result: when start vbox, Error message still there: Cannot connect to the network interface '\DEVICE\{5D1B39D4-EABA-4970-B7C5-7ACB02F884C7}'
ifconfig keeps same.
Can't ping host from guest, and to guest from host either.

Deleted HostOnly #2, edited #3 following you.
This concerns me. You should not have a number following the name. Delete all of the host-only adapters, reboot the host and add a new one but do not edit it in any way. Then post the results of the following.
- VBoxManage list hostonlyifs on the host
ifconfig -a from the guests terminal.
Oh and the guest should be shut down completely, not saved state while you are performing the tasks with the exception of the ifconfig from the guest.

Perryg,
Thanks for your time.
But my problem is still the same. I did as you said - delete host only adapters, and created new one.
Result is like below:

This still isn't right. Did you change any of the settings of the host-only interface? By default they should be 192.168.56.*
You also seem to be using a static address in the guest host-only which is not a good idea unless you know what you are doing.
