Re: [Qemu-stable] CentOS 6.4 - Updating qemu-kvm

[Steve Amerige]

Hi Michael,

The internet, indeed, is a source of rudeness as you demonstrate.  But, 
I meant no disrespect and am frankly surprised at the vigor of your 
response.

I am using CentOS, not RHEL. I provided system configuration information 
in the hope that it would be helpful (certainly not to boast). And, I 
have been hunting for a long time to get answers and hope to find some 
answers.  Rather than flaming the question immediately, please just ask 
a question directly back to me for clarification and I will do my best 
to answer.  In other words, give me the benefit of the doubt.  If it 
isn't worth your time, don't bother responding.

I went to the qemu-kvm website because I thought it might be the place 
to learn more about how to get the latest qemu-kvm on my server. Was I 
wrong about this?  I see that there are several mailing lists and 
figured the one named "stable" is for stable releases of qemu-kvm. 
Should I be using the qemu-users mailing list for this kind of question?

I have already asked the CentOS community (as the links I provided 
show), and I haven't gotten anywhere.  So, I figured to come to the 
source: qemu-kvm.

Again, if you know how I might solve this problem, I look forward to 
hearing from you.  If you have any questions regarding anything I've 
asked, please don't hesitate to ask me for clarification.

Thanks for any help!

Enjoy,
Steve Amerige
