Hello,

i meet issue while starting linux VM on windows host. it hangs with black screen and blinking prompt and nothing happens for hours...

i tried many action based on post i could find on this forum but no success :'(

any clue would be greatly appreciate! see full log start from cold state to acpi extinction in attachment,

any help welcome ty

(and sorry for my bad english)

The first thing I'd do is change the graphics RAM allocation to 128MB, and give the VM 2 cores (not more).

I'm also not convinced that a generic Linux template is correct. What is the guest OS?

Ty for your answer,

i'm not sure to remember (last reboot was few month ago...) well but i think was a centOS , i'm trying to start with different Template.

i modified parameter you suggest on vram,

When I type centos in the "Create Virtual Machine" wizard's "Name" box, Red Hat 64-bit appears in the Version box. Try letting the "Create Virtual Machine" have its way, just tweak processor, RAM and Video RAM counts, let all the other hardware be as it comes.

hello,

i tried with same result,

Please post a new zipped vbox.log showing your changes.

is the new log,

is there a way to attach the vdi to a new linux vm that already has boooting vm, and mounting fs to retrieve the data?

i juste need to get datafile and controlfile from my database to make a copy on new server,

Seems to be doing the same as it was before.

Yes, you can add this VM's disk to another working VM to get data off it. You might also be able to open the VM's disk file with 7-zip on the host OS. Under certain circumstances 7-zip can open VDI's to extract files.

Hello,

i couldn't with 7zip cause of multiple partition on the vdi,but i managed to retrieve my data with another soft

ty for your help on my request !

I rather doubt that the number of partitions was the issue. More likely is that 7zip simply doesn't understand the EXTx filesystem using by Linux. I would only ever expect a Windows archiving tool to work with with Windows/DOS filesystems, assuming that they support the container format too of course.

What alternative did you use? That was a good chance to give useful info back to the community.

I have an Ubuntu Budgie VM on my Windows 10 Home host, I started it and ran 'mount' in its terminal to get the disk's file system, which reported as ext4. After shutting down the VM I opened the vdi in 7-zip on the Windows host and was able to navigate the disk folders and extract readable text files.

It seems 7-zip can interpret at least one non-Windows file system and extract files to Windows. The disk was not a snapshotted disk, though.

Interesting, thanks. As I said I would not expect that. What version of 7-zip did you use?

Also: if they have invested time in exploring non-Windows filesystems then surely there's no way they'd be thrown by there being more than one partition.

My 7-zip is on version 19.00 dated 02-21-2019. I have tried some Linux VMs' vdi's at various times, some open some don't. Haven't seen a pattern yet.
