HyperVM is ok, there support is outright rude, and there is some bugs in the software itself.
At the end of the day, you get what you pay for.
The bug that Selectbyte encountered was specifically with openvz, and had nothing to do with hyperVM, and we actually tried our best, as in, we logged into his server for free, and checked everything, and isolated the problem to either a bug in openvz or a hardware fault, and explicitly told him so. At this point of time, we are not in a position to fix openvz bugs, though we can actually help you isolate it. The description for hyperVM specifically positions it as a technology agnostic web based management software, and that while we will do our best to help you with your problems, we expect you to be knowledgeable about the core virtualization technologies that you ultimately rely on.
Now regarding hyperVM itself, for properly reported bugs, our average turnaround time has been 30 minutes. We have currently delivered more than 500 updates, and has not broken a single installation, and this actually would be a record in the industry, considering how webhostingtalk is replete with horror stories of 'control-panel-updates-breaking-the-entire-system'. We are so confident of our software that, if you find a bug in a hyperVM which we don't fix it in within a period of 3 days after your submit your report to our forum, we will give you unlimited licenses for free. Yeah, we are bringing back the good old days of Real Programmers(TM). :-)
Vis-a-vis support: A possible problem with our support is that it is provided directly by the developers themselves, and is 100% free. I think our language is a bit more technical, and it is possible that the geekish manner in which our responses are constructed could be construed as rude. All the exchanges are publicly readable in our forum, and can be verified, and you will see that SelectByte is the only client who found us rude. Almost everyone else found our support to be too knowledgeable by industry standards, which is only to be expected, considering that it is the developers themselves who are answering the questions.
Support has improved, yes I have to say - software just keeps getting better and better. I judged too soon, good luck HyperVM
I went through our forum, and I think the misunderstanding happened because I forgot to put a smiley after a statement I had made in jest. It would be dumb on our part to pointlessly antagonize a customer, and if something of that sort happened, it was inadvertent. Anyway, thanks again for your support. We were busy providing support for the last month or so, and we are now back adding features. So if you have any requests, you can ask in our forum. We are adding new features every day now.
