Please make virtual machine jobs self-contained instead of having to connect to the Internet to retrieve job parameters.

My family's microwave oven makes my Wi-Fi connection unreliable. I have tried using the 5.8 GHz band to avoid the microwave oven, but the walls in my house absorb that range too much for that band to be of any use between my computer and where the network router with the Wi-Fi access point is located, so I am forced to use the 2.4 GHz band which the microwave oven wrecks when it is in use. Each time a virtual machine job starts from the beginnning and the microwave oven is running at that time, I get a computation error because the VM could not get the job parameters from HTCondor.

BOINC handles unreliable connections much more gracefully than your current VM applications, and I would like that grace to be added to your project.

Yes.

At least lengthen the timeout period the client waits till it decides internet connection is down for good. Or make it wait/reset/wait/reset every hour until the 30 day deadline runs out. I don't understand the reason for erroring out and dumping if it's only network ping failure. Just don't calculate credit for period it sits waiting on internet access.
