Hello everybody, I tried to measure the performance of the available drivers for windows as a HVM guest. I used the gplpv drivers 0.9.11-pre17, the PV drivers from Novell, and the drivers from Citrix XenSource with the XenServer 5. The Novell and gplpv drivers were more or less at the same speed, for both, network and disk performance. The disk performance was about 10MB/s reading and

...f the following sequence of events occurs: 1. ''xm save domain domain.chk'' 2. ''xm create domain'' 3. ''xm shutdown domain'' 4. ''xm restore domain.chk'' ? If not, I''m thinking of trying to implement into the windows gplpv xenvbd driver something along the lines of writing a magic hash of the date, time, and whatever else we can fit in 512 bytes to a certain sector, inside a file that the (usermode) service reserves for such a purpose, on ''save''. On resume, before we let xenvbd accept commands from the ope...

Hello List, Merry Christmas to all !! Basically I''m trying to boot a Windows 2008R2 DC HVM with 90GB static max memory and 32GB static min. The node config is Dell M610 with X5660 and 96GB RAM and its running XCP 1.1 Many times the node crashes while booting HVM. Sometimes I get success. I have attached the HVM boot log of successful start. Many times the node hangs as soon as the

Hi, During the install of the univention.de-signed GPLPV drivers (gplpv_Vista2008x64_signed_0.11.0.308.msi) on my Windows 7 guest, I get a BSOD "DRIVER_IRQL_NOT_LESS_OR_EQUAL" in xenvbd.sys. Afterwards, Windows won''t start. I''m now trying to do a System Restore. I will try not installing the VBD driver afterwards and see if the others do work. Full BSOD: http://jbeekman.nl/bsod20120117_1953.png ~ #xl info host : jethro release...

I''m been busily converting the xenpci and xenvbd drivers from WDF to WDM to resolve a few issues including potential licensing problems with the Microsoft WDF and to (hopefully) allow them to function as boot drivers when doing install and system recovery. It was a fairly major rewrite of xenpci, and xenvbd, which are now working (booting and ru...

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,

...SOD on close sometimes, which I should be able to fix if I can catch it happening, but the main problem is that xenpci 0.9.8 (probably) isn''t going to work with xennet 0.9.9, and when windows upgrades the drivers it will know that it has to upgrade xenpci next boot so it defers it (because xenvbd is using it to manage the system drive), but knows that it can upgrade xennet now, which introduces the version mismatches. I think booting without gplpv, performing the upgrade, then booting with gplpv again might be a workaround but I''m not even sure if that will work reliably, althoug...

Hi James. I go through the patch, since all its changes happens inside __xen_evtchn_do_upcall(), so I apply the patch into my 2.6.31.kernel by manual. (I was failed to merge a usable, 2.6.38dom0, since quite a lot branch needed, such as blkback, netback) But still, the blue screen shows up. Log attached. Is the timeout better than before? Beside, I think I need find some to examine my

...ught were due to Intel arch were actually due to this problem. . The vbd driver will now not enumerate ''boot'' disks (eg those normally serviced by the emulated pci ide device) unless the xenhide driver is loaded which hides that pci ide device. Without this it was possible to load xenvbd, not load xenhide, and get two windows drivers (xenvbd and pciide) running the same backend disk. Filesystem hosing was a near-certain outcome! For everyone who''s been getting crashes with xenvbd, this should fix those up. As usual, any and all feedback is appreciated! James _________...

Hello List, I have a small problem with the ring when transferring blocks the id on the response is different from the request. This is the boot up read, count 0. The guest requests block 0, it has to be located at 7c00. I go ahead and create a REQUEST with this data: ring_req = RING_GET_REQUEST(priv,priv->req_prod_pvt); ring_req->id = 9; ring_req->nr_segments=1; ring_req->operation

...l.bat should do the install, much the same as before. There is no ''stub'' driver at the moment, so you''ll be prompted for drivers for the ''vfb'' and ''console'' devices. Just ignore that for now. Without /GPLPV specified in the boot.ini the xenvbd and xennet drivers will just sit in ''Failed to start. Code 10'' state. See the next paragraph for why. Also changed in this release is a different approach to xenhide which hides the QEMU ATA and network PCI devices (and the xen devices when GPLPV is specified). Hopefully this sho...

In the spirit of ''release early, release often'', here''s another binary release... http://www.meadowcourt.org/WindowsXenPV-0.8.8.zip The only thing that''s changed since 0.8.7 is that xennet should work under amd64 again.
