There is something wrong with that log file. It reads as corrupted on my PC (100k of NULs at the start).

VBox.log file was huge so at the moment contains only last 1000 lines, hopefully this should be ok.
Everytime I am hitting the same issue. This one is the recent

Appreciate your guidance for resolution.

I'm afraid we need the complete log - beginning and end are particularly important, and so is the middle.... Please zip it up and attach the zip.

If the log contains a huge number of nearly identical lines then feel free to delete all but a couple of those lines, and indicate in the text where you did that.

Code: Select all

00:00:00.824 Host RAM: 12288MB RAM, available: 7503MB
00:00:00.885   RamSize         <integer> = 0x0000000200000000 (8,589,934,592)
First you are assigning more than the amount of *free RAM* to the guest.

Code: Select all

00:00:00.825 VRDE: VirtualBox Remote Desktop Extension is not available.
You might want to install the Extension pack

Code: Select all

VirtualBox 4.1.8 r75467 darwin.amd64 (Dec 19 2011 13:40:28) release log
00:00:45.283 Guest Additions information report: Version 4.0.10 r72479 '4.0.10'
Your guest additions are out of sync with your version of VirtualBox

All of the AHCI errors looks like you have too many drives connected to the same guest. Do you actually need all of them? IIRC the max port count is 10 and you have that and one more.

Hi Perryg,

Thank you for analysis.

MAC has initially 4 GB of RAM and it was working perfectly fine, now installed VB and upgraded RAM to 12GB, out of which 8GB is assigned to VM, do you think it might be crashing the server?

AHCI has a count of 10 and total 10 drives are connected at the moment. I tried many options by seeing the forum and hence finally reach to 10, added few with some changes, then some, finally got 10. I need only 6 as per my requirement.

This time increased AHCI count to 20 and running with next run. In the meantime please share any suggestion if you have.

Regards

If you look at the available RAM it says you have 7.5GB <approx> but you are assigning 8.5GB <approx> This is going to cause you issues. You can't starve the host of memory as that is where the VBox server is trying to run. Timing issue and a lot of other things will happen. Set it to 4 or 6 and see if it helps as well as making sure the guest and host match in Versions of VBox/guest additions. There was a lot of changes between the two. You do not need the guest additions at all but you can't have them this far off if you do use them.

I'm having a similar problem on OS 10.6.8. I downloaded and installed VB 4.1.8, installed the extensions and I'm now trying to install Fedora 16 x86_64. VB crashes if I try to verify the ISO file or if I skip that and try to install Fedora.

Attached is the last crash log.

@dbhinz,

Your issue is different. Please start a new thread.

Code: Select all
