similar to: Xen performance (very slow) problem with 4GB of RAM.

I'm trying to get a PVR-150 PCI card imported into a Xen DomU, however the driver blows up the kernel when loaded. The work around for this mentioned in various places is to use swiotlb=force on the DomU kernel. That leads to a fast and furious kernel panic. I've tried this with all Dom0 & DomU running kernel-xen-2.6.18-53.el5 kernel-xen-2.6.18-53.1.6.el5, bot x86 and 86_64

Hi, during some experiments with many guests I get crashing Dom0s because of too less memory. Actually the OOM killer goes ''round and kills random things, preferably qemu-dm''s ;-) The box in question has 128GB of memory, I start with dom0_mem=8192M (or 16384M, doesn''t matter). I also used "dom0_mem=8192M,min:1536M", but that didn''t make any

Hi, From the release notes i can read : "Note that the minimum RAM required to install Red Hat Enterprise Linux 4.92 has been raised to 1GB; the recommended RAM is 2GB. If a machine has less than 1GB RAM, the installation process may hang." Is it a joke/mistake ? :-O 1GB !!! I tested installation process with 256M / Celeron 600, seems to work ...) -- Martin

Hi.. Does anyone have any ideas how to speed up CentOS when its running as a guest OS under VMWare server?? It seems to be really slow...

Hi all, I'm having issue with my Centos 5.1 /Xen installation. I'm having some dom0 running 2.6.18-53.1.6.el5xen (x86_64). On the dom0 where the load is high (more than 70% of total system memory consumed by dom0 and domU) we have a lot of "memory squeeze ". The result is that the domU seems to be blocked (no network/no disk acces/ etc....). Looking for a solution in xen

May be someone could point me to optimal xm configuration file setting for Dell Power Edge 2950,2G RAM,One Quad CPU 2.0Ghz I need to run SBS 2003 Windows Server as a guest. I already installed it,but it appears very slow.... I mean may be there are some special good practices for low RAM machines. Thanks a lot. -- This message posted from opensolaris.org

So, I have a farm of machines runnign 7.1/amd64, all of which have 16 gig of memory in them. This afternoon, as an experiment, I altered loader.conf to have these two lines in it: vm.kmem_size="1536M" vm.kmem_size_max="1536M" This is what I do on machines running ZFS - these machines are not, however running ZFS, and do not have the zfs module loaded. I just wanted to see if

Hi, I'm installing CentOS5 on a HP DL380-G4 server with 4Gb RAM. It had SLES9 on it, and SLES9 find all the RAM. But now CentOS5 x86_64 can't find all the RAM.

Hi folks, I am having issues installing Centos 4.3 X86-64 on a Sun Fire X2100(AMD chip). It works with 2GB of ram just not 4 GB. It works with any combo of the 4 1GB chips I have. It only works with 2GB not 4GB any ideas? Thanks, Bill

Hello, I have an odd problem on a dual processor, dual core Opteron system. Obviosously it is x86_64 so should have no problem with large amounts of RAM. The system has 4 GB installed (2GB on each processor). If I boot the system with a fresh install of Debian Etch it sees all the memory fine. dmesg reports: Memory: 4107008k/5242880k available (1929k kernel code, 86836k reserved, 864k data, 176k

Package: xen-system-amd64 Version: 4.1.4-3+deb7u1 Severity: normal The xen kernel detects 3GB of memory instead of the full 4GB. When using the "normal" kernel 4GB is detected. On boot the 4GB is detected: root at ams-tc1-xen27:~# dmesg |grep Mem [ 0.000000] Memory: 3226132k/4980736k available (3426k kernel code, 788180k absent, 966424k reserved, 3312k data, 576k init) But only

Hello: I successfully installed Solaris10 nv77 x86 on my Compaq NX6325 laptop with the following specs: - Mobile AMD Turion 64 X2 TL-52 (dual core 64bit). - 4GB RAM. The installation destination was an external 120GB USB 2.0 drive. I was able to successfully boot into regular Solaris, but not into xVM Solaris. Meaning, after highlighting the xVM menu item and pressing enter, the screen turns

The fix in that bug will work better than without, but games will still crash occasionally. BTW the bug will still occur no matter how much physical RAM you have, it only applies to virtual memory.There was a mmap patch posted a month or so back that is supposed to fix the issue.But games down to a crawl on 64-bit systems with 4GB ram or greater, and the patch simply doesn't work otherwise.Not

Anybody know if the fix for the incorrect kernel behaviour that leads to data corruption will be available for RHEL4/5 kernels?

Simply press a key to stop booting the default kernel and then press 'e' to edit the entry. And 'e' to edit the line. Change the mem parameter and press 'b' to boot the kernel. (I don't

Hi all, I got the previously mentioned Dell Poweredge 2850 with 4GB RAM and Perc4e raid controller. Installation went well and the raid is pretty fast even with level 5. However I have another problem now... CentOS 5.2 only sees 256MB RAM. Googling a bit, got me to install kernel-PAE, this went well, but CentOS still sees only 256MB. Googling some more, I found a bios update was suggested and

I''m using Camping (though I suspect this applies to RoR just as well, and if you have an RoR specific answer I''d be happy to hear it, I may switch) to do a number of things for an internal application, one of which is transferring large files (~2GB each) between machines over the network. I thought the easy route would just be to make an app that when given the filename, serves

I have posted this before with not much response so I am posing the question again. Is there a solution for this very apparent issue with mod_fcgid that the "First connection is incredibly slow". It seems its b/c mod_fcgid doesnt keep at least 1 persistent connection around that this first connection needs to start up and then every other request is fast. Is there a solution to this?
