It looks like the dataplane in your vSRX device is not up.
Are you able to ping the remote peer (or anything at all)? Do you have any interfaces?
Please make sure that you use the default (and supported) VM settings, meaning 2GB RAM, 2GB disk etc. The only change allowed in the VM settings would be to add more NICs.
Also, since your are using ESXi 5.5, make sure you use Junos 12.1X47. X46 did not support ESX5.5, but only 5.0 and 5.1.
Hope it helps.
