I have a Ubuntu Server VM on a Mac OS X host. Stupidly, I have no recent snapshot of this VM (let this be a grim reminder to me).
My host was running slowly and erratically- low on RAM. While trying to change files on the VM, I received a constant "file system is read-only" error (similar to this question Ubuntu VM "read only file system" fix?). I shutdown the VM and restarted the computer, then opened Virtual Machine with no other applications running. Now, when I attempt to load the VM, I get a number of these errors on the start-up screen and then it freezes:
comm init: bad extended attribute block (some numbers here)
I am able to get to Recovery mode but don't have any experience in repairing a Linux machine. Is there anything I could do in Recovery mode, or otherwise, to attempt to save my virtual machine?
