similar to: XEN | kernel 3.0 vs 2.6.34-xen - no pci backend?

Hi, I have a question about the bug: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1632 This is marked as fixed in the pv-ops kernel. I am working for a company developing a xen based virtualisation solution. Unfortunately the design is tied to CentOS and there is resistance to upgrade to > 2.6.31 kernel. My question is whether it is possible for me to try to backport the fixes for

Hi there, After updating a server from CentOS 5.3 to 5.4 my Xen pci-passthru setup has some troubles. The server has two NICs, one used by dom0 and the other assigned to a domU and one SCSI controler assigned to another domU. It has been working fine since CentOS 5.1, when I did the initial setup. After upgrading to 5.4, I get this error when starting the domU with one of the NICs assigned:

Hello Xen folks, I use Debian Squeeze. I want to passthrough PCI devices. With the old stable Debian (grub legacy) i did not have problems. I edit /etc/default/grub like: quote: GRUB_CMDLINE_XEN_DEFAULT="quiet xen-pciback.permissive xen-pciback.hide=(00:14.2)(01:05.1)" I run "update-grub". Now i look at /boot/grub/grub.cfg: ### BEGIN /etc/grub.d/20_linux_xen

Hello I am new in XEN and Linux. I am trying the VGA passthru. I can xen-pciback.hide EtherNet, Serial Com port. But when I xen-pciback.hide my VGA. I can no longer login to the Linux(Fedora 12). Then how can I xm create a XP DomU guest? Can anyone help? I am using Intel Q35 MB with Intel Core2 CPU. _______________________________________________ Xen-users mailing list

Hi all, I were upgrading my system recently. But I met some difficult problems, the biggest one is described in http://permalink.gmane.org/gmane.comp.emulators.xen.user/66971, unfortunately I got no answer yet. My original environment is xen3.4.2(64bit) + dom0 kernel 2.6.18-xen, and 4 domus with kernel 2.6.18-xen, after first upgrade stage, I have Xen4.1.0(64bit)+dom0 kernel 2.6.32.39, and 4 domu

I am a bit confused on the PCI stuff. PASSTHRU-- does this mean that pcifront is not needed? Or only that the PCI is not limited as it is with slot. In general, none of the docs are getting me anywhere with xen 3.0.3. Example: I run this: echo -n 0000:2:0.1>/sys/bus/pci/drivers/pciback/new_slot echo -n 0000:2:0.0>/sys/bus/pci/drivers/pciback/new_slot echo -n bind 0000:2:0.0 >

Hai, I am using dell insprion 580 machine for xen installation and dom0 configuation. I compiled xen source code and configured the kernal. Grub entry given below menuentry ''Xen 4.0.0-rc8 / Ubuntu 10.4 kernel 2.6.32.25 pvops'' { insmod ext2 set root=''(hd0,3)'' multiboot (hd0,3)/boot/xen-4.0.0-rc8.gz module (hd0,3)/boot/vmlinuz-2.6.32.25 dummy=dummy

This patch enables PCI passthrough with stub domain. PCI passthrough with stub domain has failed in the past. The primary reason is that hypercalls from qemu in stub domain are rejected. This patch allows qemu in stub domain to call the hypercalls which is needed for PCI passthrough. For security, if target domain of hypercall is different from that of stub domain, it rejects hypercall. To use

Hi all, I follow instructions(http://wiki.xensource.com/xenwiki/XenParavirtOps) to build XEN and dom0 kernel. Building XEN has no problem, but there is an error which I cannot solve to build dom0 kernel. The brief instructions for building dom0 are get linux-2.6-xen code from git and make ARCH=x86_64 menuconfig, finally generate kernel.deb. (I did every step exactly as the web page says)

I am happy to announce that I have successfully (and finally!) been able to pass a PCIe graphics card via VT-d to a Windows XP HVM DomU. About time!

Hi Folks, I make I new approach to pimp up my xen-Kernel in higher version-numbers. Currently I run a selfcompiled 2.6.27-Kernel from: hg clone http://xenbits.xensource.com/ext/linux-2.6.27-xen.hg In the next step I want to run the kernel from jemery: git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git I tried the last couple of days to get pci-passtrough work with jeremys

hi, i have installed Xen hypervisor on fedora 17 and now i want to assign devices directly to a guest OS through VT-d. does any one know how can i do it? i found some solutions for that but those had some steps for when installing Xen while i installed Xen on fedora. i am going to know,can i assign device to a guest OS through VT-d capability with installed Xen on fedora 17? thanks.

Hi, All the reviews for the AMD 890fx chipset reported that it supports IOMMU v1.2. But I cannot find any mention of that on AMD site. Does 890fx support IOMMU? Do 890fx motherboards with IOMMU exist? Does Xen support 890fx?

Thanks Anna, this was also quite interesting for me. Did you mean that I just have to eliminate the else branch or raise arround "All devices behind the uppermost PCI/PCI-X bridge must be co-assigned to the same guest." or do I have to eliminate more in order to prevent an FLR (whatever that is). For my board it''s definitely necessary to move PCI devices in different guests,

Hi gurus, I used xen 4.1.0 (64bit) + dom0 kernel 2.6.32.39 (32bit) + domu kernel 2.6.32.39 (32bit) environment. I was trying to passthru Broadcom NIC to domu.
