Hi Everyone,

In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU, in /var/log/auth.log, I see:

/dev/hvc0: No such file or directory

listed a lot of times. I'm not experiencing any problems, however it makes looking through logs for auditing purposes a bit annoying.

Any ideas what this is? I think it has something to do with the "Hypervisor Console", whatever that is?

Could it be a security risk at all? As this error would also appear on VPSs hosted out to customers.

Thanks
