VBox 5.0 - Can't resume state saved machine

[markkrj]

Sadly my cpu doesn't support VT-x, nor can I activate it at the VM's settings.

Intel seems to believe otherwise?

Sadly, I can't post links, but you should look for my actual processor /products/36500/Intel-Core2-Duo-Processor-E7400-3M-Cache-2_80-GHz-1066-MHz-FSB
This is telling the true:

Code: Select all

00:00:00.986902 Full Name:                       "Intel(R) Core(TM)2 Duo CPU     E7400  @ 2.80GHz"

And this is f* lying to us:

Code: Select all

00:00:00.711492 CPUM: Matched host CPU INTEL 0x6/0x17/0xa Intel_Core2_Penryn with CPU DB entry 'Intel Xeon X5482 3.20GHz' (INTEL 0x6/0x17/0x6 Intel_Core2_Penryn)

So Intel tells me:
Intel® Virtualization Technology (VT-x) ‡ See Ordering Info

And

Code: Select all

grep vmx /proc/cpuinfo

returns false.

EDIT: Sorry, didn't read the last posts. But then, you think that turning VT-x on by command line would help? I could try it, do you know the command?

[mpack]

It's the same command you used to turn it off, except you turn it on: "--hwvirtex on".

No, I don't believe it would help, but exact form of the error message would tell us a lot.

[markkrj]

I forgot to say, I did turned it off, but once it didn't help, I turned it back on. I've just turned it off (--hwvirtex off --vtxvpid off --vtxux off) and on again (--hwvirtex on --vtxvpid on --vtxux on). The error is the same in both cases.

Failed to load unit 'CSAM' (VERR_SSM_LOADED_TOO_LITTLE).

Please provide a log for a session in which VT-x was enabled.

Well, that confirms it: no VT-x on this CPU.

God, I'm saying it since OP :/

Yes, and now you have provided data to support your assertion. Does my wish to obtain reliable evidence trouble you? In that case I'll happily stop.

Your wish for evidence doesn't trouble me. What I was bothering is, why were you trying to figure out if my CPU supports VT-x all this time? Would it be such a great help? I've already provided reliable data, since providing you ALL my CPU flags should be enough. Anyway, I downgraded to 4.3.30 and I'll keep waiting for a mature product to be released. I'm not saying that it should support all hardware, even because my CPU is old, and I really should have one with VT-x support. But I'm seeing a lot of Ubuntu users having troubles with this release. Maybe it's too new yet. Some maturing will be good. Anyway, thanks for your time and help.

I have exactly the same problem, non VT-x CPU, Windows 7 SP1 x86.
I create new VM, save state and can't resume with the above error message.

5.0.0 BETA 3 was the last that had resuming saved state working.
All later betas and RCs don't allow resuming on my system.

The CSAM saved-state bug will be fixed in the upcoming 5.0 maintenance release.

When? Is there a prerelease build for me to use and test if needed?
