Do I need to compile only DBVM UEFI or also dbvm?
What software is used to do this? How to open .cproject and .project?

Linux enviuronment and eclipse with the CDT extension (c development environment), and the gnu efi library
I also recommend getting the latest vmdisk.img from CE (don't use the one in the video either, has the same AMD bug there)

I compiled DBVMUEFI.EFI and vmdisk.img but now another error, did I compile on VMware or do I need to compile on real hardware?

looks like I added some more non-amd compatible code.
See the line: UINT64 debugsilicon=readMSR(0xc80);
remove it, or replace it with 0. it's just some debug info I wanted to check but its only valid on Intel (there may be more of those)

I commented out 2 lines because when compiling, it complained about the second one.
// UINT64 debugsilicon=readMSR(0xc80);
// Print(L"debugsilicon(0xc80)=%lx\n",debugsilicon);
I couldn't find any more lines like that

Find
s=readMSR(0xc80);
Print(L"readMSR s=%x\n",s);
and remove it (as I said, there's more)
(Tip, just look where the debug output stops. It's usually around there)

Print(L"Reading msr 0x10:\n");
s=readMSR(0x10);
