Hardware virtualization supported but no vmx or svm flag? – ToraCat's Eye
http://blog.toracat.org/2010/12/hardware-virtualization-supported-but-no-vmx-or-svm-flag
A view from a sleepy cat. Hardware virtualization supported but no vmx or svm flag? One common method to verify that the system has the hardware virtualization extentions (Intel VT or AMD-V) required for full virtualization is to look into /proc/cpuinfo like:. Egrep '(vmx svm)' - color=always /proc/cpuinfo. There was an intriguing post. In the CentOS forums . Apparently he has a VT-capable CPU but it did not show up in /proc/cpuinfo. When he tried Fedora, it was there. Then more recently, a post. Discard...

A view from a sleepy cat. Leap seconds – who cares? A leap second will be introduced at midnight on June 30, 2012. The last time this happened was on the New Years Eve in 2008. One might say, “OK, I will get to the next appointment 1 second ahead, good! 8221; So who cares? The code has been fixed since. Make sure your kernel is newer than kernel-2.6.18-164.el5 (RHEL/CentOS/SL). RHEL/CentOS/SL 6 kernels are not affected. 1] http:/ ask.slashdot.org/article.pl? June 24, 2012 at 10:09 pm.

http://blog.toracat.org/2013/04/customizing-welcome-message
A view from a sleepy cat. Customizing welcome message in RHEL/CentOS/SL. You can have the MOTD (message of the day) display messages that may be unique to the machine. One way to do this is to create a script that runs when a user logs on to the system. First, create a script, make it executable, and save it in /etc/profile.d. Here is an example script named mot.d:. Next, edit /etc/ssh/sshd config. This will disable motd. Now restart the sshd service. When you log in, you’d see something similar to:.

Discard that ‘discard’ — Run fstrim on RHEL and rebuilds – ToraCat's Eye
http://blog.toracat.org/2014/07/discard-that-discard-run-fstrim-on-rhel-and-rebuilds
A view from a sleepy cat. Discard that ‘discard’ — Run fstrim on RHEL and rebuilds. If you have an SSD drive on your system, you may have added the. Option in /etc/fstab which will discard blocks not in use by the file system. Another way to achieve this is to use the fstrim. Command. Red Hat recommends use of fstrim over the discard option [1]. There is a nice article about TRIM [2] that explains why:. The article also describes some other advantages of fstrim. 2] http:/ blog.neutrino.es/2013/ho...3 Res...
