...y default. LPFC is a kernel module for the Emulex HBA card. To compile these two kernel modules, I downloaded and installed kernel-2.6.9-55.el5.src.rpm, which is the full kernel sources (with xen patches) for RHEL 4.5. However, compiling pcifront and lpfc against the kernel sources did not succeed. CONFIG_XEN_PCIDEV_FRONTEND=m and CONFIG_SCSI_LPFC=m. These kernel modules do not have any dependencies. It appears that CONFIG_XEN_PCIDEV_FRONTEND is not supported in the 2.6.9-55kernel source code for RHEL 4.5. Due to production requirements, I have to stick to RHEL 4.5 as a guest. The alternative is to use the 2.6.18-8 xe...

Hi, everyone! We google a lot, but can''t find how to config the pvscsi on our ubuntu13.04 PV on HVM.There are some links http://wiki.xen.org/wiki/Paravirtualized_SCSI http://wiki.xen.org/wiki/Xen_Configuration_File_Options And we use the config option above Configure PVSCSI devices vscsi = [ ''/dev/sdc, 0:0:0:0'' ] I pass sdc to the hvm, but in our pvhvm (ubuntu13.04)

Hi all! I want to assign a physical network card (e100) to a domU: I think Dom0 is ok but domU does not recognize the pci nic. into DomU I don''t know wath should I see: I have nothing in dmesg nor in messages... Into Dom0 I have this modules.conf: options pciback hide=(0000:03: 08.0) install e100 /sbin/modprobe pciback; /sbin/modprobe --ignore-install e100 This is dmesg: pciback

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, I want to perform pass through I/O from my domU. I guess I would need an additional network card for the same. Is there any preference on the second network card I should get or any one is fine? I have a x86_64 machine with Cent OS 4.4 running. Are there any additional considerations that I cannot see - Kindly let me know. Thanks, Asim _______________________________________________
