I''ve installed Xen Hypervisor 3.0.3 (CentOS 5.7, i386) inside Virtualbox 4.1.16 (Mageia 1, i686) and have noticed that Dom0 is consuming 85% of the memory allocated to the VM (1GB) so I''d like to reduce this as much as possible in order to make more room for one or two VM''s. Is there a minimum amount of vRAM that can/should be allocated to Dom0 (using the dom0_mem boot

I am trying to get a pv_ops dom0 working for testing, but I am running into an elf_init error: (XEN) *** LOADING DOMAIN 0 *** (XEN) elf_init: not an ELF binary Full output attached. >From what I have read on the mailing lists, it seems that it is usually a problem with either grub or a corrupt dom0 kernel. Attached is my kernel config (2.6.28-rc6-tip). I followed the instructions on:

I gave the AMD64 version of 7.2 RC2 a spin and all installed as expected off the dvd INTEL S3200SHV MB, Core2Duo, 4G of RAM In the past it had been suggested that for zfs tuning, something like vm.kmem_size_max="1073741824" vm.kmem_size="1073741824" vfs.zfs.prefetch_disable=1 However doing a simple test with bonnie and dd, there does not seem to be very much difference in

I am having problems getting my 64-bit Debian Squeeze (Xen version 4.0, Linux Kernel 2.6.32) dom0 to recognize a harddrive connected to a secondary sata controller. My motherboard is a Gigabyte GA-X79-UP4 and has two sata controllers. The first is controlled by an Intel X79 chipset and the second is controlled by a Marvell 88SE9172 chip. During the initial install of Debian everything is fine and

Hi there, I have a question regarding PCI passthrough on the Citrix XenServer 5.6 (Xen 3.4.2). I already managed to get some soundcard passed through to a Windows guest. So I think my knowledge about that topic isn''t _that_ low. But I cannot seem to pass through a SATA/PATA controller to a Linux guest. I have some additional CD/DVD burner (PATA) attached to a SATA/PATA controller

I think I finally have nailed down the problems with TFTP on the 4.10 branch, and so I have released 4.10-pre20. Please let me know if you have hardware on which 4.05/4.06-pre3 works, and 4.10-pre20 does not. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.

Hey, Are there any known issues with the Intel''s integrated HD graphics 4000? I just bought a new laptop and have tried everything I can think of to get Xen to load. After choosing Xen in GRUB, it just boots to a black screen. There is no error message , no dmesg output, nothing. I have no idea what is causing this problem. I''ve gotten Xen to install with no problems on another

I just installed centos 5.5 x86_64 on a new HP laptop. It has the core i5 processor. only 1 cpu is detected should be 2. This has happened before. Is upstream not keeping up with new processors released and updating the kernel? I'd rather not go through the process again of putting a newer kernel on the machine and having something different out there than "stock" centos. Jerry

Ok, I do see they had a series of MegaRAID SATA 150-xx and 300-xx cards, these were 64 bit PCI or PCI-X cards. 95Q9 does not appear to be a valid card number, 9240, 9260, 9280 are some pci-express SAS MegaRaid

I have a raidz2 and did a scrub, it took 8h. Then I reconnected some drives to other SATA ports, and now it takes 15h to scrub?? Why is that? -- This message posted from opensolaris.org

Greetings, I''m attempting to do gfx_passthru with the primary graphics adapter (03:00.0), passing it to a guest. I can unbind it from the host but when I fire up the guest OS my monitor loses signal from the graphics card and that''s that. The GFX card is dual DVI, I''ve tried both slots. Host is Linux 2.6.32.14-1.2.105.xendom0.fc12.x86_64, Guest is Windows 7. PC is an

Hi, I am having problems with the nouveau driver from Debian. Can I get help here? Cheers

Wei, Quick question: Am I reading the code correctly, that even with per-device interrupt remap tables, that GSIs are accounted to the intremap table of the corresponding IOAPIC, presumably because the IOMMU sees interrupts generated as GSIs as coming from the IOAPIC? In that case, then we need all devices sharing the same IOAPIC must not have any vector collisions. Is that correct? -George
