similar to: Multiple IRQ''s in HVM for Windows

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

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 am having problems with save/restore under 3.3.1 in the GPLPV drivers. I call hvm_shutdown(xpdd, SHUTDOWN_suspend), but as soon as I lower IRQL (enabling interrupts), qemu goes to 100% CPU and the DomU load goes right up too. Xentrace is showing a whole lot of this going on: CPU0 200130258143212 (+ 770) hypercall [ rip = 0x000000008020632a, eax = 0xffffffff ] CPU0 200130258151107 (+

Recently our automated testing system has caught a curious assertion while testing Xen 4.1.5 on a HaswellDT system.

When I install Windows Server 2003 Standard Edition on Xen, I didn''t configure multicore (vcpus = 1, cpus not set). Now I''d like to fully utilize multicore, but whatever I set, windows task manager can not see more than 1 cpu. Do I have to reinstall the OS with vcpus and cpus being set properly? Since the image file is licensed, is there any way I configure windows to show multi

Trying to boot my Thinkpad T30 with Solaris snv_81 xVM it get the error message This version of Solaris xVM does not support this hardware The output of "echo ::interrupts | mdb -k" while booted without xVM is bash-3.2# echo ::interrupts | mdb -k IRQ Vector IPL(lo/hi) Bus Share ISR(s) 0 0x20 14/14 - 1 cbe_fire 1 0x21 5/5 ISA 1 i8042_intr 3 0x23

I''ve just uploaded 0.9.11-pre7. save/restore should be working for 32 bits on both SMP and UP, and maybe for 64 bits although it''s not tested. If someone could test migration it would be much appreciated. The installer seems to not install the drivers under 64 bit environment... but they can then be installed manually. Not sure why at this point.

Hello! Has anybody experienced network latency problems with combination of Windows 7, GPLPV drivers and RDP connection? Any Windows pop-up message(such as "command not found" error message in "Run command:" dialog, or dividing by zero in windows calc) causes a short freeze of RDP session and looks like that from dom0: PING 192.168.44.65 (192.168.44.65) 56(84) bytes of data.

''cat /proc/interrupts'' in a Linux PV domain shows interrupts starting at 256 and labelled as ''Dynamic-irq''. Are these available in a HVM domain, eg under Windows?

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

Hi, Keir, These patches are rebased version of Yunhong''s original patches, which were sent out before XEN 3.2 was released. These patches enable MSI support and limited MSI-X support in XEN. Here is the original description of the patches from Yunhong''s mail. The basic idea including: 1) Keep vector global resource owned by xen, while split pirq into per-domain

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

Hi, DomU is a Win2008 R2 64 When i install the GPLPV drivers the network latency goes from 15ms to random numbers up to 1200ms and eventually dies. If you run a ping from the DomU to another host the network stays alive but the high latency is still there. Further more if i try and uninstall the network driver i am unable to use the old one (realtek) as it cannot detect the device.

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

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

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

''xm block-attach'' doesn''t let me assign the same backend device anymore, even if I use ''r!'' or ''w!''. I think this has changed since 3.1.1 (or maybe since 3.1.0). Is this the way it is supposed to work? Thanks James _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com
