similar to: How does domain (smp) scheduling work?

Hi all, My Ct's box is RH 3.0 SMP kernel EM64T. They are asking if OCFS for SMP (EM64T) is available or not. In following site, we can not see OCFS for SMP (EM64T). http://oss.oracle.com/projects/ocfs/files/RedHat/RHEL3/x86_64/1.0.14-1/ ---------- ocfs-2.4.21-EL-1.0.14-1.ia32e.rpm OCFS driver for kernel version 2.4.21-27.EL and higher (EM64T) ocfs-2.4.21-EL-1.0.14-1.src.rpm OCFS driver

If you have an AGP video card which you aren't actually using you can try selecting the minimum possible AGP apperture (window whatever) size (possibly even disable it?). This might help. Also removing the AGP card and using a junk 1-8MB svga card will also possibly work. In my experience the linear framebuffer of video cards is by far the greatest memory hog these days. Cheers, MaZe.

Hi, I''ve just attempted several times to install Fedora Linux domU''s on a Fedora 6 [32-bit xen kernel 2.6.20-1.2944], and it keeps crashing at various points when trying to format domU''s virtual disk. I''ve tried allocating 1 vcpu and 2 vcpus, and it still keeps crashing dom0. The machine has a total of two hyperthreaded 3.2ghz Xeon cpus, and 3GB of RAM.

Hi, I''ve got a HT-enabled dual-preocessor Xeon machine, on which I''m running xen-3.0-testing. I''ve specified entries like the following in the configuration scripts for DomU''s to prevent them running on CPU 0: cpus = "1-4, ^0" My question is 1. Does this type of specificaiton mean Dom0 would *always* be running on CPU0? Please note that this

>5. LTP testing might run very slow in SMP VTI Domain with credit scheduler. If binding VTI >and Xen0 vcpu, this bug won''t be there. Hi keir, In credit scheduler, two vcpus in the same domain may be scheduled on the same CPU. For instance, vcpu0 and vcpu1 are running on the same CPU, vcpu0 is doing spin_lock in guest, then time slice is due, vcpu0 is scheduled out before doing

Hi Booting my Xen Dom0 on Debian Etch (Kernel is the prebuild one from bits.xensource.com), I found that only one cpu core (of two: dual core) is recognized by the (dom0-)Kernel. Googling this issue, I found on xen-devel-list that xen kernel is named smp but isn''t really doing so. Is there any (prebuild) kernel that I can use for smp? Thanks Gregor Reich

Hi, I''ve played a little bit with the xen scheduler to enhance the performance of paravirtualized SMP domains including Dom0. Under heavy system load a vcpu might be descheduled in a critical section. This in turn leads to even higher system load if other vcpus of the same domain are waiting for the descheduled vcpu to leave the critical section. I''ve created a patch for xen

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

Sorry for alI these individual emails, but I think is more readable this way, by having each independent information in a separate email. I also have these additional cards that I can try: Gefoce GT 1030 and Geforce GTX 1050 Ti. I have tried Geforce GT 1030 and it is working nicely but without hardware acceleration. Without the hardware acceleration I am able to get into X (Ubuntu Mate 17.10)

This may not be the best place to ask, but I was prompted by a question about guest cores on KVM. We currently use VMWare Server (v1.0) on CentOS5. It supports up to two virtual CPUs, but not very well, as I understand it. VMWare Server 2.0 might do better at supporting the same maximum of 2 CPUs, but if my research is correct, they both use what is called "strict co-scheduling".

Hi Ben, Ok! I've removed nvidiafb from kernel config. Now linux is able to boot with the msi Geforce GT 710 card and eventually ends up displaying a slightly distorted lightdm login screen. The mouse cursor moves, but never changes to typing cursor mode when hovering the password input box, and I am also unable to enter the password, some graphics glitches in the login box too. There are

Hi I am developing Window pv network driver and hit a problem now. My server use Xen 3.1.4 and have 2 physical CPUs. When I create two VM with 1 VCPU on a same server, iperf performance is OK between those two VM, but there is performance degradation between those 2 VM when i increase VCPU from 1 to 2. This problem occurs in QEMU mode too. Does Xen 3.1.4 has such problem or anything wrong

>but if I disable hyperthreading (noht on the kernel line in lilo/grub) Could the same result could be obtained if hyperthreading is disabled from the BIOS ? Supermicro Motherboards (most Phoneix based) have this option Also, would we see same pops and clicks in a dual CPU box (Zeon) then ?

The xen_play_dead is an undead function. When the vCPU is told to offline it ends up calling xen_play_dead wherin it calls the VCPUOP_down hypercall which offlines the vCPU. However, when the vCPU is onlined back, it resumes execution right after VCPUOP_down hypercall. That was OK (albeit the API for play_dead assumes that the CPU stays dead and never returns) but with commit 4b0c0f294 (tick:

Hello, I am running Samba 2.2.2 with acl-0.7.16 on RedHat 6.2 (2.2.19). The PDC is a Windows 2000 Server and the Samba server is a domain member using Winbind. All the workstations are Windoze 2000 Pro with SP2. Everything seemingly works fine but every day or two I get a runaway SMBD process which hogs the CPU and becomes unkillable. The only resolution is to reboot the server completely.
