the last one is because the file does not exist
Hi @hector-cao were you able to check it? Any news ?
@diegoara96 Hello, we are still working internally to figure out the issue, please be sure that we take this issue seriously. I will keep you posted as soon as we have some news
@diegoara96 - can you tell me if you had all of the attestation components (DCAP, ITA) installed as well?
@bktan8 when the problem happened we were using release 2.0 with everything by default and the attestation packages installed with the setup-attestation-guest.sh script.
We have not experienced this error again, so I understand that it can be closed.
we can't reproduce either. Thanks @diegoara96!
All of our VMs with more than 2 weeks of life time stopped working at once. We are still able to create new ones and they work but the old ones do not work at all. The log message we have is as follows:
I don't know if there are any more log files that I can give you.
