failed to access perfctr msr(msr coo1ooo4 is 0) Debian VM

[bgandy94]

As of today, I get an error saying "failed to access perfctr msr(msr coo1ooo4 is 0) " when trying to boot my Debian VM inside virtual box, after loading through the rest of the screen, it goes to a black screen, starts to resize to bigger and lower multiple times before just freezing and not booting at all. I've tried reinstalling virtualbox, I've tried restarting, I've tried creating a fresh install of Debian and still get the same error.

Any help? I'll attach a log

This is not an error but a warning and should not have an effect on the guest. However the missing guest additions can. Does the guest start in console mode?
Also it appears that you are implying that it used to work and if that is the case what changed?

As far as I know nothing has changed. And so how do I readd the missing guest additions? Also, how do I test it in console mode?

Yes it works from a command line start.

[Perryg]

Then from the command line install the guest additions and see if that brings it back.

[bgandy94]

Can't install the package, it's saying that the machine cannot resolve the ftp server. And I can't ping anything

[Perryg]

You need to start the network stack since you are in command line but you don't need it to install the guest additions unless you have a new install and are missing the necessary packages to build external modules.

This should help Howto: Install Linux Guest Additions

If you need the packages just use ifconfig to start the stack.

I remember what has changed since the last time I booted the system. I set a different user account to be the owner of /var instead of root. Could this be the issue?

[Perryg]

Yup. Why would you change that? System folders must be owned by the system ( root )

[bgandy94]

Well, I changed ownership back to root and it's still bugging out.

[Perryg]

It does not work that way. Did you do a recursive chown? Did you use root:root?

Anyway this is far beyond the scope of this forum. You need to ask Debian how to fix the permissions or just install again and don't change system permissions.

[bgandy94]

Well then I guess my question for you is, why when I reinstalled a new instance of debian, it still didn't work?

[Perryg]

How would I know that? You would be the only one that can answer questions about your install. In general a new install should work but it depends on the version of the guest and a lot of other things.
I suggest you install again and keep records as to what you do and where it fails. Post that along with any error messages, log files, and then we might be able to see what is happening.

Got it figured out. Thanks
