Hi all, I wrote a pass (attached). But I get a runtime error: buse at buse-VB:~/Desktop/llvm-2.7/lib/Transforms/CG_CFG$ opt-2.7 -load ../../../Release/lib/_CG_CFGGen.so -CG_CFGGen < ../../../buse/simpleCode.bc > /dev/null 0xa7bae0: 0 libLLVM-2.7.so.1 0x00007f4a8b6add1f 1 libLLVM-2.7.so.1 0x00007f4a8b6ae36d 2 libpthread.so.0 0x00007f4a8aa98b40 3 _CG_CFGG...

The target VM will have several buses to which disks can be attached. Commonly it will have an IDE bus, and possibly a virtio-blk "bus" (not really a bus) and/or a SCSI bus. Virt-v2v does not model this at the moment. Disks are just added to the output XML in the order that we write them, and so they can move around with r...

Hi, I saw that Xen support a translation between device/intx to GSI for a single PCI bus, I thought about adding multiple PCI bus support but disregard the bus information so the same device/intx on different buses will be OR wired to the same GSI, sounds reasonable? What other things do I need to support in Xen in order to add multiple PCI buses, assuming that secondary buses holds only PCI/PCIe devices? Thanks, Guy. _______________________________________________ Xen-devel mailing list Xen-devel@list...

I think you're right. Each bus requires some amount of IO space, and I thought I recalled someone saying that all of the available IO space is exhausted after 7 or 8 buses. This was in relation to PCIe, where each root port is a bus, and can potentially take up IO space, so possibly in t...

I am trying to create a QEMU MIPS guest, so that I can test some code for big-endian safety. Every attempt to create a MIPS guest is giving me an error: Unable to complete install: 'XML error: No PCI buses available' It seems like this is a known issue. https://www.redhat.com/archives/libvir-list/2016-May/msg00197.html However, I am still getting this on a fully updated Fedora 25 system with libvirt-2.2.0-2.fc25.x86_64. -- =================================================================...

Hi, My goal is to assign PCI addresses to a number of devices (network interfaces, disks and PCI devices in PCI-passthrough) without delegating to libvirt the generation of those values. This should give me more control and for sure more predictability over the hardware configuration of a virtual machine and consequently the name of the interfaces in it. I'm using libvirt 4.3.0 to create

...nymore if we can use ACPI to "black-list" the incompatible virtio devices. Reason: hotplug. To my understanding, the ACPI DRHD tables won't change during runtime when a device shows up or disappears. We would have to isolate virtio devices from the rest of the system by using separate buses for it (and avoid listing those in any DRHD table) and enforce that they only get plugged into those buses. I suppose that is not desirable. Maybe it's better to fix virtio /wrt IOMMUs. Jan -- Siemens AG, Corporate Technology, CT RTC ITP SES-DE Corporate Competence Center Embedded Linux

...or big-endian safety. You are probably better off using PPC64 which is big-endian and much more widely tested in libvirt than MIPS, so actually likely to work reliably. > Every attempt to create a MIPS guest is giving me an error: > > Unable to complete install: 'XML error: No PCI buses available' > > It seems like this is a known issue. > > https://www.redhat.com/archives/libvir-list/2016-May/msg00197.html > > However, I am still getting this on a fully updated Fedora 25 system > with libvirt-2.2.0-2.fc25.x86_64.

...;ve got a Cheetah that's a few years old, and having pulled it out of another server (in the datecenter), I put it in this box to zero it out for reuse... and the box refuses to see the drive. *Nothing* in dmesg, *nothing* in /var/log/messages, and I tried echo "0" etc to get the SCSI buses to rescan. Anyone have any ideas? mark

I'm having some trouble here - need some help! I've just bought a TE405p (32-bit 5V), but cannot get it working in a dell 6450. The dell has (from tech specs) "three peer PCI buses: two 64-bit buses and one 32-bit bus Expansion slots seven hot-pluggable PCI slots (two 64-bit/66 MHz, four 64-bit/33 MHz, and one 32-bit/33 MHz)" I cannot get the card working in any of the slots. When I power the server up, the digium card blinks red for a second, and the dell pci light g...

This patch series adds stable bus and slot numbers for removable drives (CDs and floppies) when the guest is converted using virt-v2v or virt-p2v. Previously we were a bit random about this. After this patch series, the bus and slot numbers and preserved if at all possible. BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1238053 Rich.
