Hi XEN-Community, I''m trying to build the actual version of the XEN gplpv (win-pv) drivers. I use the a Windows XP machine with the WinDDK 7600.16385.1 and Wix 3.0 like suggested in the BUILD.txt The building process itself seems to be working, at least there are no compiler error. (I just made the "makedist") Instead, the final *.msi files and the drivers itself are nowhere

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

Is there currently a way of preventing filesystem corruption if 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

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. I have problem with installation XCP and XenServer on DomU. Installation just stuck after a while from installation beginning. DomU just stop responding, even reconnect with vncviewer isn''t possible. I''m using iso images to install. Dom0 is kernel 3.6-rc7 with xen 4.2.1-pre. I''m having such log: -videoram option does not work with cirrus vga device model. Videoram

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,

Note: I could simply direct boot the appropriate kernel/initrd to get the alpha1 installation going as always done in the past, but I think this should work. The Debian alpha 1 installer page says it should. Details $ sudo xm create -c wheezytest.cfg Using config file "./wheezytest.cfg". Error: Boot loader didn''t return any data! direct pygrub test run: # pygrub

All, Is is possible for xm create foo.cfg to traverse a symlink to access the foo.img. Here''s an example config and the resulting error.. --- name = "jim" memory = "512" disk = [ ''phy:/dev/VolGroup00/foo,xvda,r'', ''tap:aio:/home/fred/local/jim/build/foo_swap.img,xvdd,w'',

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 running without crashes so far). I

I''ve just uploaded a new binary release of the GPL PV drivers for Windows - release 0.6.3. Fixes in this version are: . Should now work on any combination of front and backend bit widths (32, 32p, 64). Previous crashes that I thought were due to Intel arch were actually due to this problem. . The vbd driver will now not enumerate ''boot'' disks (eg those normally serviced

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:

This one just fixes the install.bat problem that Jim pointed out. http://www.meadowcourt.org/WindowsXenPV-0.8.3.zip James _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
