similar to: CPU cap

Currently with the credit scheduler, cpu_weight cannot be assigned to guest domains at boot time.(it can be set with xm sched-weight after booting) This patch allows CPU weight, and CAP to be set by the Xen configuration files. Specification: The following can be added to the Xen configuration files. 1.CPU WEIGHT [OPTIONAL] cpu_weight = cpu weight value -sets the cpu time ratio to be

On a 8 Core system only dom0 can set cap > 100 and vcpus > 1. On a domU ''xm sched-credit -d <domU> -c 200'' says "Error: cap is out of range". Vcpu cannot be set higher than 1 - regardless of boot/config/command line. Low performance is equivalent to the cap setting. See ''xm list --long'': (domain (domid 0) (uuid

Hi Everyone, How can I make use of xm sched-credit in a VPS hosting environment? Can I use "xm sched-credit -d <domain>" in a script at system startup, or does this have to be run after the respective guest has been started? Also, what happens when the guest is shutdown then restarted, or rebooted? Do I need to run that command again? If so, how would I automate this process?

Hi Everyone, How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04. Can I still use the CD? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This is because the names of parameters differ between a SXP file to

Hi Everyone, I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide: http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/ Now, using the new kernel that it gave me, the system doesn''t seem to be able to detect vt-x.. In virt-manager, Local Install Media and Network Boot are greyed out.. Any ideas? Thanks

Hi all, I''ve a linux dom0, a dom1 winxp sp2 (WinXP) and another winxp sp2 with 2 vcpu (WinXP_02) Dom2 uses all the dom0 idle: I mean this vm uses too much resources, it seems something wrong in configuration. This is strange because the other win xp uses very few resources I''ll attach some useful output.. Suggestions? (domain (domid 4) (on_crash restart) (uuid

Hi Everyone, In my HVM guest''s config file, I have given my guest 3 interface. I have called them fw1, fw2 and fw3. I have joined each interface to a bridge on the Dom0. This does appear when I do a "brctl show". However, there are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where x is the domain ID for the guest). Furthermore, I am only able to run

Hi Everyone, In Xen, is a DomU able to access data in RAM which a previous DomU has stored in the past, but didn''t "zero" it? I understand that this is a problem with physical disks (using phy:/), just wondering if the same stands with RAM Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated: Each Node: Dell R210 Intel X3430 Quad Core 8GB RAM Intel PT 1Gbps Server Dual Port NIC using linux "bonding" Small pair of HDDs for OS (Probably in RAID1) Each node will run about 10 - 15 customer guests Storage Server: Some Intel Quad Core Chip 2GB RAM (Maybe more?)

Hi Everyone, To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter? Or is there something else I am missing? Thanks _______________________________________________ Xen-users

Hi All it is possible to tune dom0/domU for better IO/network performance? Since I have changed to Cenots7 dom0, I have a really poor IO performance inside a PV VM. I have already done what is described on http://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance It is better now but still significantly worse than with centos6 dom0 my settings: xen parameter: dom0_mem=1024M cpufreq=xen

Hi Everyone, I have a Xen host (Xen 3.4.2) which is running CentOS 5.5 Dom0. I wish to install Dell OpenManage to get a nice web interface with hardware status. Do I need to do anything special to get this working on a Xen host? Or does it work out of the box? The reason why I''m asking, instead of trying, is that my server is currently on its way to a colo, and I won''t have

Hi, I''ve installed xen-unstable 4.2 from actual git (last commit was 4dc7dbef5400f0608321d579aebb57f933e8f707). When I start a domU with xm all is fine include the cpu_weight I configured in my domU config. When I start the domU with xl then all my domU have the default cpu_weight of 256 instead of the configured one. Was the name of cpu_weight being changed for xl command ? My domU

Hi Everyone, In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU, in /var/log/auth.log, I see: /dev/hvc0: No such file or directory listed a lot of times. I''m not experiencing any problems, however it makes looking through logs for auditing purposes a bit annoying. Any ideas what this is? I think it has something to do with the "Hypervisor Console",

Hi Everyone, Does anybody have any experience using pfSense on Xen? I would most probably have to use HVM... My idea would be to use PCI-Passthrough to the pfsense DomU, and only make the Dom0 accessable via the pfsense firewall Thanks Jonathan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Everyone, This is going to sound silly but... I''m just off the phone with a Microsoft SPLA reseller. They sell licenses to run Microsoft software in a hosted environment. I was asking about obtaining Windows licenses to run on my Xen VPS hosting solution. Maybe there is a big misunderstanding, but I''m faily sure she said that it was illegial for me to rent out Xen

I have xen 3.2 running on an 8 core server. I tried to set xm sched-credit -d mydomain --weight=1024 --cap=800 and got: Error: cap is out of range. I thought 8 cores are 800% ?! So, do I have du use 100 (for 100%) instead of 800 (for 100%)? And what about vcpus in my domu config? Must I set vcpus when cpu_weight is set? If yes (e.g. vcpus = 2) does this restrict cpu_weight only to 2 cpus?? Very
