Hi, I am trying to configure two identical systems with the following setup. dom0: Centos 6 OS on Apple Xserve i7 server with PCI cards for 4GB FC (LSI FC949ES) and 10GB Ethernet (Intel 82598EB) dom1: Centos 5 OS with passthru mode of PCI 4GB FC and 10GB Ethernet (ixgbe and mptfc blacklisted in dom0) Everything starts ok, but networking in dom1 using the 10GB interface has extremely high rtt

I was reading the Wiki page here: http://wiki.xen.org/wiki/VTd_HowTo don''t know how updated it is, BUT at the top it said: -------------------- -------------------- -------------------- -------------------- -------------------- -------------------- _Xen 4.1 xl tools notes _ * Only devices with FLR capabilities are supported. * Passing through a PCI card without FLR capability

Hi all, Recentlly, I have installed a Windows 7 Enterprise kvm guest under a CentOS 5.4 kvm host (fully updated) using virtio drivers and all works ok except two things: sound and vga resolution. a) How can I increase vga resolution to 1440x900 or is not possible to configure more than 1024x768 when virt-manager is used?? b) I have assigned a sound device to this windows guest (ac97)

I previously reported this on the centos mailing list: http://lists.centos.org/pipermail/centos/2009-November/085672.html And I've found out that Red Hat has backported the VT-d support from Xen 3.3 to RHEL 5.4. http://lists.centos.org/pipermail/centos/2009-November/085677.html It seams to me that the "classic" Xen pci-passthru (up to Xen 3.2) works only on some minor cases as

Hi everyone, I'm trying to send a FAX with the following configuration: Analog FAX machine (OKI) <----->SPA21000<----->LAN<----->Asterisk<--------> PSTN I'm restricted to use passthru mode for faxing, instead of T.38 protocol, because the Asterisk box is running v1.2 and cannot be changed as it is in a heavy production environment. Anyway, it "should"

Hi, The following 4 patches enable direct device assignment (PCI passthru) for HVM guest on AMD IOMMU platforms. Please apply them against C/S 16491 as the named order. To enable AMD IOMMU, please add "enable_amd_iommu" as xen boot parameter. 1-cleanup.patch: code cleanup, bug fix, minor enhancements to existing amd-iommu codes. 2-passthru-amd.patch: passthru support, modifications to

Hi, My environment is as below: Hardware: Dell R210 NICs: Broadcom NetXtreme II BCN5709/5716 (w/o FLR) Xen: xen 4.1.2 Kernel: 3.6.32.57 (final version of xen community) Distribution: Centos 6.2 (upgraded to above kernel) When I added iommu=soft to domU kernel boot line, the PCI passthru-ed NICs can be UP and RUNNING. Otherwise, omit iommu=soft option would make the passthru-ed NICs only UP but

Dear All, I'm trying to install a Debian Wheezy KVM guest on a CentOS 6.4 Host. The only resolutions supported are 1024x768 or 800x600. I increased the video RAM to 500 MB, but the guest still says: [ 10.321] (II) CIRRUS(0): Not using default mode "1920x1200" (insufficient memory for mode) Only 32 MB are recognized: 00:02.0 VGA compatible controller: Cirrus Logic GD 5446

Hi, everyone. I''m Guilherme Suzuki (brazillian, by the way) and really interested in xen-vga-passthru. Lately, I bought a brand new Saphire HD 7950 (OC Boost) because I saw in a wiki somewhere that users have been able to passthru these VGA devices to domU (win7, win-xp and so on). But, after I installed it, I executed *lspci -vv* to check if FLR in DevCap was present (which

GizmoChicken, Read that there's a problem with Nvidia GeForce GTX cards and both Xen and KVM, like it's not on a Nvidia whitelist, I'm a bit concerned. From the ArchLinux thread I've seen some success with Nvidia GeForce GTX cards, this is confusing. The bit I read here was: " That would mean you are stuck with the GTX for that, but Nvidia nerfs their cards to stop

Question: Is there a method to allow NT logons to 'passthru' a Samba system??? It is necessary for me to hide a number of Win95 systems behind a linux system running ipmasq. All of that works o.k., but, for the life of me, I can't seem to figure out how to avoid having logon scripts run twice. I have placed the scripts in appropriate places on the linux system, thinking that

Dear All, what settings do you use in KVM for Linux guests? The resolution with VNC / VGA is 1024x768 only. If I choose Spice / QXL the resolution is better, but colors aren't displayed properly and some letters are missing! In the Debian guest I installed the packages xserver-xspice and spice-client-gtk, but it wasn't better. So how do you configure KVM-guests with graphical
