Hi, I'm building a test asterisk server and building the latest kernel I got to wonder if there are any specific recommendations about schedulers and so forth for optimum performance. There are a few areas that raise questions in my mind and I wonder if anyone has any opinions/comments on which settings are most suitable for use with asterisk: SLAB Allocator (SLAB or SLUB?) Tickless

Greetings- I'm running some USB DAHDI hardware on a system with a tickless kernel. The audio quality is quite poor. Could the tickless kernel be to blame? If so, when recompiling a kernel that is *not* tickless, is there a recommended KERNEL_HZ value? IIRC, older kernels used to be 1000, but newer ones are 250. Thoughts? --Tim

Hi all, If you are using the kernel divider= option in your vmware quest, you are probably aware of the bugs reported at: https://bugzilla.redhat.com/show_bug.cgi?id=315471 Someone @redhat "confirmed" the fix is in the test kernel -92. I tried it but it seems to have the same problem as before - when used with clocksource=pit, it hangs on bootup. Wonder if some of you can test this

I have a beefy machine (Intel dual-quad core, 16GB memory 2 x GigE) I have loaded RHEL5.1-xen on the hardware and have created two logical systems: 4 cpus, 7.5 GB memory 1 x Gige Following RHEL guidelines, I have it set up so that eth0->xenbr0 and eth1->xenbr1 Each of the two RHEL5.1 guests uses one of the interfaces and this is verified at the switch by seeing the unique MAC addresses.

Hello to everyone on the list, I have upgraded my RHEL4 to RHEL5.1 yesterday (all updates have been applied to it as well). I used to have dovecot v0.99.11 on the old system. Everything was working fine. Now I have 5.1 and its respective dovecot v1.0.rc15. Upon upgrading to RHEL5.1, dovecot no longer works correctly. The first thing I did after rewriting the config file for the updated version,

Hi, I am running CentOS 5.3 32bit as a VirtualBox 3.0.0 guest running on Windows XP. The Windows host CPU usage is constantly at 50% although the CentOS guest is completely idle (i.e. 0.00 load average). I know this is a common problem related to the 1000Hz frequency that the CentOS kernel runs at. With previous versions of CentOS, I used the kernel-vm package [1] and it solved my problem.

Hi All! I''m using RHEL5.1 in a guest domain and with kernel 2.6.18-53.el5xen. Is need the source of this kernel to compile an application, someone knows how do I get this source?

Hello, I am trying to build a custom kernel 2.6.24 from ubuntu with xen dom0 support. Does Xen support a tickless system (CONFIG_TICK_ONESHOT=y) and the realtime features of this kernel (CONFIG_PREEMPT=Y instead of CONFIG_PREEMP_VOLUNTARY)? Everytime, I set these options while configuring the kernel, the two settings are not regarded during kernel compilation. I also tried to build the

Hello, We have installed RHEL 5.2 Server ( i386 image ) on a machine with 64GB of RAM. When booting the default PAE kernel ( 2.6.18-92.el5PAE ) that is shipped with RHEL 5.2 installation the OS detects 64GB of RAM. But when booting the Xen kernel ( 2.6.18-92.el5xen ) the OS detects only 14GB of the total amount of available RAM. Did anyone encounter this problem before ? Is it a normal

Under 4.6, we recompiled the kernel with HZ=100 for improved time-keeping in VMware guests. I've read about the backporting of the divider patch into RHEL/CentOS 4.7, but it sounds like it also comes with some bugs. I have been unable to determine the current status of the divider option in the latest 4.7 kernel update. I have experimented with "divider=10" and it works with no major
