similar to: Dynamic-irq''s in HVM domains

Hello James, I am doing quite rigorous torture tests with Xen and GPLPV. Let me first repeat the test setup: Use Xen 4.1.1 and kernel 2.6.32.36 (commit ae333e9). Configure 2 HVMs called VM1 and VM2 as follows (per HVM): 2 VCPUs, 2 virtual disks, 1024 MB RAM, viridian=1 Install Windows 2008 R2 SP1, do install everything twice - never clone. Install GPLPV, iometer 2006.07.27, prime95 26.6 x64,

I really need to have the ability to tie event channel port''s to interrupts for my gplpv drivers under Windows. Is anyone working on anything like this? Does MSI allow more than one interrupt per PCI device?

What is the state of GPLPV and Windows 8? I am currently running tests with Windows 8 and GPLPV rev956 and operations (disk IO, net IO) look good. There seems to be a problem with shutdown/reboot where Windows hangs somewhat and displays a warning about improper shutdown on next reboot. Regards Andreas

I''m just doing some testing on the gplpv drivers with different ways of handling interrupts, and I''m trying a scheme where each xen device (eg vbd/vif) driver attaches to the same IRQ as the pci driver, and each handles it in sequence. In testing though, I noticed the following when logging what each ISR is doing: 60.32381439 - evtchn event on port 5 60.32384109 - port 5

I''ve recently noticed that my windows crash dumps fail at around 40-50% under GPLPV. ''xm dmesg'' shows the following: (XEN) grant_table.c:350:d0 Iomem mapping not permitted ffffffffffffffff (domain 865) At first I thought that the cause was just a bug in my grant ref code but it just occurred to me that this could be happening when Windows tries to write out the

I''ve been looking into bug [1]#195 and I have a couple of questions on how timer interrupts and virqs are handled. Is it possible for dom0 linux to irq balance timer interrupts to different cpus? That is, if xen sends a VIRQ_TIMER to vcpu0, backed by cpu0, is it possible for that interrupt to be handled by vcpu1, backed by cpu1 ? After putting in some debug code in to timer_interrupt

Hi, We have some problems with Xen 4.0.1 and resinzing of lvm volumes. When I resize a lvm volume with "lvresize -L+50G -n /dev/data/windows-data" the Windows Dom U don''t scan the new size of the lvm volume. The only way to see the extend is to halt and create the DomU We have try with sign and unsigned drivers gplpv, with Windows 2008 and Windows 2003 server :

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine

We need to write the irq number to GICC_DIR on the physical cpu that previously received the interrupt, but currently we are doing it on the pcpu that received the maintenance interrupt. As a consequence if a vcpu is migrated to a different pcpu, the irq is going to be EOI''ed on the wrong pcpu. This covers the case where dom0 vcpu0 is running on pcpu1 for example (you can test this

Well, I seem to have developed a strange issue with the GPL PV drivers in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two of them, though, have started exhibiting a strange behavior with intermittent network connectivity. Basically, the network starts up and connects initially. After some

Hi all, I have a Toshiba Tecra M9 and have not been able to boot it dom0. This is running SXDE 01/08, snv79b. After booting under kmdb and setting moddebug=80000000 before booting the Solaris kernel (with help from Dan Mick), I was able to see mac_ether as the last thing loading, right after loading the e1000g driver. I cannot drop into kmdb via F1-A after it hangs. I''ve also

I''ve just made my first ever attempt at an Nullsoft installer, so if you want to try it download "Xen PV Drivers 0.9.5.exe" from http://www.meadowcourt.org/downloads/ The installer should detect the version of windows you are running and install the drivers. At the moment you''ll need to install the shutdown monitor service manually, but you can do that from the start

Hello, All, Today one of our servers was crashed, after I rebooted the server, one vps can not boot up, and it needs fsck, after I run fsck command, a lot of files lost, and also some file content was changed. Not sure how could it happen, do you have any advice that can avoid this or recover the data? Thanks. _______________________________________________ Xen-users mailing list

Is there a way to get Windows to do an orderly shutdown (eg simulate a power button press) using the ''xm shutdown'' command? Thanks James _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With

I''ve just uploaded 0.9.11-pre12 of the GPL PV drivers for Windows. Since -pre10 (and -pre11) I''ve fixed a heap of crashes that were plaguing xennet under load, and also rewritten the interrupt/event distribution logic to improve performance. Under windows 2003 I can now get network speeds of 1-2Gbit/second TX and 600Gbit/second RX, which is considerably better than I was
