Failed to get VM handle #3

Closed caiovlp closed 3 years ago

caiovlp commented 3 years ago

I used to use vmread to read a win10 kvm on a arch 5.6 and it worked really well. I now have a fedora 5.9 and vmread doesn't seem to support it as it's been discontinued. I'm trying to get memflow kvm connector to work but keep getting:

inv: 0x258ec60 2020-12-17 16:28:48,922 ERROR [memflow_ffi::util] connector error: Failed to get VM handle conn: (nil)

Not sure where to start looking into it. Tried running as root as well. Any ideas?

Hey, and welcome aboard! Did you install the memflow kernel module? Is it loaded? Does dmesg say smth in the lines of memflow: initialized when you load it? I know these are very basic, but worth mentioning.

What if you tried changing permissions with sudo chmod 777 /dev/memflow? If this works, it means it's just a permissions issue. Running as root should have worked, not sure why it didn't.

If nothing works, please let me know more about your setup, it should work on fedora :)
