The unstable tree now includes support for SMP guests, i.e. domains which run on multiple cpus. SMP guests can use between 1 and 32 virtual cpus, even if the machine has fewer physical cpus. The code is highly experimental and performance will improve over time. To use SMP guests: - enable option CONFIG_SMP in the Linux 2.6 kernel config - dom0 will boot with upto the number of physical cpus in

I have a 2 way machine. Soliciting folks opinion on whether it makes sense to smp enable DOM0 so that IO handling can be balanced over both CPU''s... Opinions?

Hi, I'm currently thinking of putting more functionalities to Linux server box. Major is Asterisk, but would also like to add video surveillance, home automation and limited (for only domestic up to 4 users) web, file and mailserver apps. I know there are problems running Asterisk with other such apps on same machine - but wonder if I can take advantage of dual processor machine in this

Hi all (and Mr. Dunlap in particular), I have a question about the credit (and ultimately credit2) scheduler that I hope you can help me with. I have read the white paper "Scheduler development update" and as much material on the credit scheduler as I can find, but I am still not completely clear on how I should think about the cap. Example scenario: Server hardware: 2

Existing credit scheduler is not power aware. To achieve better power saving ability with negligible performance impact, following areas may be tweaked and listed here for comments first. Goal is not to silly save power with sacrifice of performance, e.g. we don''t want to prevent migration when there''re free cpus with some pending runqueues. But when free computing power is

One of my users complained that his Win2kSP2 complains that his password Is going to expire in 8 days. A while ago we changed from Win2k domain to a Samba 2.2.3a controlled domain. How do I disable the password expiration? I read the man pages and searched Google but couldn't find any hints about the issue. It almos seems like this expiration thing should not be happening at all...?

Is it possible to run php4 and php5 parallel in Centos4 somehow? If the parallel php5 could be installed from rpm also that would be great also. Regards, Peter

I started to receive this kind of messages a few days ago on one of my servers: Message from syslogd@ at Mon Apr 29 08:02:55 2013 ... server1 kernel: EDAC MC0: UE row 0, channel-a= 0 channel-b= 1 labels "-": (Branch=0 DRAM-Bank=0 RDWR=Read RAS=0 CAS=0, UE Err=0x2 (Aliased Uncorrectable Non-Mirrored Demand Data ECC)) I've never had ECC memory to fail on me before, so now I am

I need to do a new CentOS net install on a new server having the Supermicro X7DVL-3 motherboard: http://www.supermicro.com/products/motherboard/xeon1333/5000V/X7DVL-3.cfm Based on that info I assume the board having a "8x SAS Ports via LSI 1068E Controller". We received the server with 3 drives + 1 spare as hw RAID-5 preinstalled. During bootup I see that the drives are initialised

Hi all, I would like to monitor the power consumption of my server. What I am looking for is: * a simple monitoring device that would measure the power consumption of 1 server * a way to get the consumption reading from that device to my centos server (via usb / wlan / whatever works) Any suggestions? Best, Peter

Dear all, In my applications, the real-time performance is very important, so I used 4 containers, with only one application running in each container and a physical CPU core is only dedicated to one lxc. and I must know which container is hosted by which CPU core. That is, I need to pin a specific lxc to a specific CPU core. I can achieve this in a native linux system by the following xml

Hi, Does anyone have experiences about ARC-1883I SAS controller with CentOS7? I am planning to have RAID1 setup and I am wondering if I should use the controller's RAID functionality which has 2GB cache or should I go with JBOD + Linux software RAID? The disks I am going to use are 6TB Seagate Enterprise ST6000NM0034 7200rpm SAS/12Gbit 128 MB If hardware RAID is preferred, the
