Cannot start corectld

If I try to start the server via corectld start -d I receive the following error.

goroutine 1 [running]:
panic(0x4742240, 0xc820179450)

Any ideas on how to solve this?

Hi! some quick questions

a) how did you build the blob / where did you fetched it?
b) macOS version, hw version
c) can you confirm that in current tip issue persists on your setup ?

Thanks in advance!

Hello!

a) Sorry I did not get the question
b) macOS Version is 10.11.5 on an iMac (27, End of 2012, Intel Core i5)

Thank you for your help!

ok - translating a) how was your binary built ? homebrew ? make from local git checkout ?

I installed it with Homebrew using brew install corectl like mentioned in the Readme.

[AntonioMeireles]

Seems like my CPU does not support EPT, right? 😢

I was able to figure out that the file /etc/exports is causing the problem.
So did mv /etc/exports to /etc/exports.bak
Once I moved it to /etc/exports.bak it ran without an issue.
I don't know much about networking or why this is causing an issue.

The earlier entries in the /exports.bak file seem to have been created by vagrant
