Gpl Pv Drivers For Windows
Needs Review Important page: Some parts of page are out-of-date and needs to be reviewed and corrected! About These drivers allow Windows to make use of the network and block backend drivers in Dom0, instead of the virtual PCI devices provided by QEMU. This gives Windows a substantial performance boost, and most of the testing that has been done confirms that. This document refers to the new WDM version of the drivers, not the previous WDF version. Some information may apply though.
Benchmarking GPL PV Drivers for Windows between 0.9.11-pre13 and 0.10.0.69 In reply to this post by jim burns Since I don't have particularly fast equipment, the significance of these numbers will be in the relative difference between the.
I was able to see a network performance improvement of 221mbit/sec to 998mb/sec using iperf to test throughput. Disk IO, testing via crystalmark, improved from 80MB/sec to 150MB/sec on 512-byte sequential writes and 180MB/sec read performance. With the launch of new Xen project pages the on www.xenproject.org keeps a lot of the more current information regarding the paravirtualization drivers. Supported Xen versions Gplpv =0.11.0.213 were tested for a long time on Xen 4.0.x and are working, should also be working on Xen 4.1. Gplpv =0.11.0.357 tested and working on Xen 4.2 and Xen 4.3 unstable. 05/01/14 Update: The signed drivers from ejbdigital work great on Xen 4.4.0.
If you experience a bluescreen while installing these drivers, or after a reboot after installing them, please try adding devicemodelversion = 'qemu-xen-traditional'. I had an existing 2008 R2 x64 system that consitently failed with a BSOD after the gplpv installation. Switching to the 'qemu-xen-traditional' device model resolved the issue. However, on a clean 2008 R2 x64 system, I did not have to make this change, so please bear this in mind if you run into trouble. I do need to de-select 'Copy Network Settings' during a custom install of gplpv.
Leaving 'Copy network settings' resulted in a BSOD for me in 2008R2 x64. I run Xen 4.4.0-RELEASE built from source on Debian Jessie amd64.
Hi Antolienplease use - a new & separate disk for test (because of disk fragmentation issue) - a HDD-Size = 2 x (your RAM in your phy. Is this different than 0.9.8's behavior? I am running 0.9.8 right now and VT-d is working fine. My pass-through device is a USB controller. If 0.9.9 will break it, I need to hold off on the upgrade.

VT-d PCI passthrough is currently broken with the current GPL PV drivers. The 0.8.9 driver behaved differently and didn't block my PCI passthrough device. Xen-users mailing list. Hi, I have a Windows 2000 HVM install on which I'm trying to install the GPLPV drivers.
I followed the process, restarted, and put the /gplpv in a copy of my os boot line. The thing is, there are no errors, but nothing really changes. Looking in my device manager, nothing looks different.
I still have one unknown PCI device, which has a Xen device ID from looking in the registry. None of the devices show the gplpv drivers installed.
I tried manually searching for drivers in the gplpv drivers folder for the unknown PCI device, but it couldn't find any. My install is on a 5G LVM partition I made, along with a extra 5G LVM I attached to the win2k OS. I installed from a standard win2k installation disk, and had a SP4 disk to update the OS after install. Am I missing Xen devices that should be listed or something?

This should get around any problems of mixing version, but will still allow 'xm block-detach' etc to work. I think I may have fixed a BSoD on shutdown too (0x9f). To upgrade to 0.9.9, you might be able to get away with booting without /gplpv and performing the upgrade, otherwise you'll need to remove all trace of the drivers (see wiki) before installing I've been tinkering with signing the drivers (just with a self-signed cert for now). It seems to work okay I'm just working on putting it into the build script.
One thing I found is that on my test server I had signed 0.9.8 and so the unsigned 0.9.9 wouldn't automatically install as windows prefers a signed driver over an unsigned one. Keep that in mind if you've been signing drivers yourself! Anyway, this release should be a lot more stable that James Xen-users mailing list Xen-users mailing list.
Hi James, I have no problems with an exclude inf file, sounds like that's the best solution for now if xen changes PCI id's between versions. Anyone else have any suggestions? - Original Message - From: James Harper To: Darren Foo; Sent: Monday, June 16, 2008 5:35:54 AM Subject: RE: Xen-users RE: Release 0.9.9 of GPL PV Drivers for Windows Hi JamesWill it be possible to change the drivers to block only certain network devices instead of all PCI devices?
VT-d PCI passthrough is currently broken with the current GPL PV drivers. The 0.8.9 driver behaved differently and didn't block my PCI passthrough device.
It should be possible, I'm just not sure what the best approach is at the moment. I guess maybe it isn't so important for network devices, I'm just concerned that if I make the criteria for 'pci storage device' more specific, eg 'pci storage device with pci id xxxx:yyyy', and qemu changes them, then very bad things happen. I have seen qemu give slightly different pci id's to devices under different versions of xen. I'm thinking that an exclude list in an inf file would probably be best, at least in the interim.

It will be a little tedious to change but at least it can be done without a recompile being required. But I'll give it some more thought. Any further suggestions appreciated:) Thanks James Xen-users mailing list. HiI have a Windows 2000 HVM install on which I'm trying to install the GPLPV drivers.

Someone else reported this, and found that the reason was because the inf files were only compatible with XP and above. Can you please try the following for each.inf file: 1. Under Manufacturer, duplicate the.NTx86 line but change.NTx86 to.NT 2. Duplicate the xxx.NTx86 section but change the.NTx86 to.NT 3. Try to install. If it doesn't work, also duplicate the SourceDiskNames.x86 section but remove the.x86 If it works, and doesn't break x86 and amd64 (please test), let me know and I'll update my inf files.
I'll try it myself when I get time but that may not be for a bit. James Xen-users mailing list. You need to set TestSign mode in boot options. bcdedit /set testsigning yes Uhm, and don't forget to add the CA-Cert you are using (on self signed the cert itself) to users AND systems trusted root ca's using mmc snapin certificates. I've created the following in hg: 1.
Signsys.bat - signs the sys files (see makedist.bat for use) 2. Signinf.bat - generate catalog and sign it based on inf files 3. Signconfig.bat.template - modify and copy to signconfig.bat If signconfig.bat exists then makedist.bat will do the signing stuff. The installer.nsi file currently depends on the.cat files though, I need to make that optional. So the user configuration required is: 1. Set up the appropriate certs in their store 2.
Copy signconfig.bat.template to signconfig.bat and put their cert names in there 3. Run makedist.bat One thing that's missing though is a way to extract the CA cert from the store based on the name specified in signconfig.bat.
Do you know offhand the incantations to do that? Once I can do that I'm almost ready to do the next release I think. James Xen-users mailing list. I modified all of the inf files after installation. I performed the three things you listed, but it still would not install. When I removed the.NT from the duplicate xxx.NTx86 sections altogether (no extension), it accepted the driver.
I ended up with a Xen PCI Device Driver, a Xen Net Device Driver listed with my regular net adapter, and 3 Xen Block Device Drivers listed alone in SCSI/RAID (2 HD, 1 cdrom presumably). However, when I boot into GPLPV mode, I get a BSOD as follows: STOP: 0x000000D1 (0x00000114, 0x00000016, 0x00000000, 0xBFFA1558) DRIVERIRQLNOTLESSOREQUAL.

D'oh, yes, I was remembering incorrectly. Before I can make the changes to the.inf files in the source, I need to be sure that the change doesn't break 2003 x32 or 2003 x64. Are you able to test?

Unfortunately that's just a fairly generic crash. Because the crash is occurring in scsiport.sys it almost certainly means that you won't be getting a crash dump. Unless you can build from source and get intimate with the debugger, you'll have to wait until I can have a look. No guarantees about when sorry. If I get time before then I'll have a look through the scsiport stuff and see if it makes any references to differences between 2000 and 2003. Thanks for following up.

Do you know offhand the incantations to do that? Once I can do that I'm almost ready to do the next release I think. Okay I figured that out. Now I just need a way for the installer to install the certificate (semi-)automatically.
There appears to be a way to bring up the 'view cert' screen with a simple rundll32 call, but I'm not sure that that will get it into the 'localMachine' store where it is required.

Therefore, you can install iometer (dynamo) in Dom0 and connect another instance of iometer running on any windows (only the GUI) connecting to the 'worker'-dynamo. So, you can compare the results of the native iometer with the windows-xp-hvm iometer results.
