similar to: qemu-dm: unregister_iomem() broken?

We created a 64bit SLES11 SP1 guest, and then used a script to change memory (using mem-set command) periodically (in 1 second): set 1G, set 2G, set 1G, set 2G, and so on. After a few minutes, we encountered QEMU exit due to SIGBUS error. Below is the call trace captured by gdb: The call trace: Program received signal SIGBUS, Bus error. 0x00007f94f74773d7 in memcpy () from /lib64/libc.so.6 (gdb)

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very

I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

Keir, This patch fixes cirrus and rt8139 co-exist issue in new qemu-dm. The root cause is that if two MMIO spaces are continuous, qemu may misuse last MMIO space''s read/write to handle current request.

Hello everyone, Can you please tell me if it is possible in LLVM to cast a `Value*` to an `Instruction*/LoadInst*` if for example `isa<LoadInst>(MyValue)` is true? In my particular piece of code: Value* V1 = icmpInstrArray[i]->getOperand(0); Value* V2 = icmpInstrArray[i]->getOperand(1); if (isa<LoadInst>(V1) || isa<LoadInst>(V2)){ ...

Hi friends, I have a matrix with following format. group var1 var2 .......varN c1 group1 1.2399 1.4990....-1.4829 c2 group4 0.8989 0.7849.....1.8933 ... ... c100 group10 ..... I want to draw a profile plot of each condition c1 to c100, which rows in above matrix and each line representing a row should be uniquely colored according to the group(1 to 10). I think this is simple task

Hi All, When tried to pass through 2 mpt2sas HBA to hvm guest, hvmloader paused with below: MPT BIOS Fault 09h encountered at adapter PCI(00h,04h,00h) Press any key to continue... Checked related codes and mostly like it caused by rombios did not loaded MPT BIOS properly, and lead MPT BIOS failed to bootup. config-file of the guest as below: ---------------------------------- # cat vm.cfg

Hello R people, I have a data file with 101 numeric variables: one variable called IDN (the individual's unique id number, which I need to retain, and which ranges from 1000 to 1320; some numbers are obviously skipped), and V1 to V100 (each has a value of 0 or 1; these 100 variables represent sequentially ordered days and whether a characteristic was present or absent--e.g., v1 is day 1 and a

Hello all, Not sure if I am completely missing something but here goes. I have XCP 1.0 running without any issues. I have the mtu set on both the storage network, the corresponding PIF, and the VIF to 9000 and when displayed in ifconfig it shows that this is indeed true. I have several CentOs 5.6 VMs running in HVM mode (i.e. no xen kernel) which attach to the the storage network through these

Hello all Xen devels, I''m writing howto''s in brazilian portuguese language about Xen-3.3.0 stubdom, pv-grub and others configurations. Following what is written in xen-3.3.0/stubdom/README, I tried start a HVM but without success. When I start the virtual machine calling ''xm create hvmtest'' command, in a few seconds the virtual machine is dead (see

Hi xen developers, Does any of you know how to disable the cirrus-vga emulation for hvm in xen? I have been trying to disable that from the source codes, but even with that, I still see a VGA controller when I boot up my guest domain. In particular, I would like to do this because I am passing through a graphics card to my guest domain using direct pass through. Thanks, - billy

Hello, I am currently trying to suspend a HVM domU via ACPI. However, after "xl trigger vm s3suspend" the virtual machine freezes after 2-3 seconds (I get a prompt at xl console before that!), and keeps printing the following lines: [ 240.428145] INFO: task jbd2/xvda1-8:146 blocked for more than 120 seconds.

Hi everybody, Wanted to hear your opinion and to receive a smart advice. I'm trying to use virt-v2v in order to convert ova image (exported from vcenter) to run on libvirt/kvm - all this inside a VM of fedora. The converted image is also a fedora. During the conversion process, in some point of libguestfs activity, I get double fault panic from L2 (printed as part of libguest output) and the

Greetings Xen user community, I am interested in using Mellanox ConnectX cards with SR-IOV capabilities to passthrough pci-e Virtual Functions (VFs) to Xen guests. The hope is to allow for the use of InfiniBand directly within virtual machines and thereby enable a plethora of high performance computing applications that already leverage InfiniBand interconnects. However, I have run into some
