A guide on how to install KVM on CentOS 6 with X installed
With my new CentOS 6 web server I’ve decided I want to leave SELinux switched on if I can get everything configured correctly. In the past I’ve always switched it off but a little extra protection is always preferable.
This error is due to the language your browser sends to the server during the HTTP request.
Many times I’ve gone to hit CTRL-K, S in a JOE session to save changes to a file but missed the “K” meaning I actually sent CTRL-S to the terminal which sends a “stop flow” signal.
Both my network monitoring servers suffered this condition over the 2wks my company takes holidays for Christmas so I returned to work to find 2 VMs consuming 6ghz of CPU between them. A quick check of top showed mysqld_safe consuming 100% CPU on both VMs for no apparent reason.
I extracted a tarball which had applied 777 (rwx) permissions to all files and directories that it contained. I wanted to set all files to 644 and all directories to 755, but there were too many levels to do it manually so I needed to do it through a shell script.

I had a CentOS 5 Hyper-V VM running on Windows 2012 / Hyper-V 3.0 on which I mistakenly installed the Linux Integration Services 3.4 using the RHEL57 packages. The installation completed with some warnings and the initial reboot was OK, but after removing the "microsoft-hyper-v" and "kmod-microsoft-hyper-v" the VM would no longer boot due to a kernel panic.
After upgrading a CentOS 5.5 Hyper-V VM to CentOS 5.9 (or RHEL 5.5 to RHEL 5.9 / 5.10) you get a kernel panic when booting with the new kernel. If you select the old kernel from the GRUB menu, the server boots as expected.

I installed CentOS 7 on my HP MicroServer Gen8 and found the network speed was restricted to 100mbps even though I was using Cat5 cable with a gigabit switch. The solution was to disable Network Manager and modify the NIC config file.
I wanted to enable basic roundrobin NIC teaming on my HP MicroServer Gen8. This configuration allows load balancing and fault tolerance. When transferring data to the server it will only be received via 1 NIC meaning a 1Gbps limit, but when sending data it will load balance over both NICs meaning you can achieve up to 2Gbps. A future article will describe how to enable 802.3ad LACP aggregation which will provide 2Gbps data transfers both ways. This post will also work on RHEL 7.
