I use Citrix XenServer 5.5 and on a Windows Server 2008 R2 Guest there is installed Xentools 5.5, for a year all works well. After a restart we get a BSOD with Stop Code 7B, it is a problem with the Citrix pv-driver I think, but how can I delete this driver without GUI, safe mode also bring up a BSOD.
So I install a second Windows Server on same VM and can access the filesystem of the Guest. In the Windows/System32/driver I delete xenvbd.sys and scsifilt.sys in the registry I delete everything I found with xenvbd or scsifilt, but the BSOD is still here.
The Windows Startuprepair and sfc /scannow dosent help. Update: All known Snapshots are with the same Issue. If you install the Xen PV driver on a guest and you get the BSOD with stop 7B it is possible that the driver is corrupt or some files are missing. First you should find out the version of the driver: go to filesystem and get properties of - for example - xenvbd.sys then go to your XenTools Installdisk and search for the following Files: xenutil.sys xenvtchn.sys xenvbd.sys scsifilt.sys After copy this files to Windows System32 Drivers you can start your Guest in safe mode. Now you can install a newer version of the Xentools from safemode (you find a install file on Xentools that works also in safemode) and you will get some errors. Don't reboot your server.
Deinstall this Programm now and a cleanup will starts, all corrupt or missing files and registry Entries will delete and cleanup your installation. Now reboot and it works! I'm glad the problem is resolved, and I'm upvoting the question. Not because the solution would be of any redeeming value to others, but due to this should serve as a cautionary tale. There are two things that should not have occurred. One, system changes that modify system files or registry settings should be validated, and that validation should include that the system and the change performs as expected after a restart. Two, 'testing' the change on a similar system or a one-off copy frequently identifies these types of issues.
Number two may not have been directly relevant in this scenario, but is frequently relevant in environments where numer one is lacking. I would speculate that the system may have worked fine if restarted after the initial change, but something was whacked in the year that transpired. This is why when I get involved in an activity that includes a system modification, my first step is to restart the server to ensure that if there are any issues like this, they aren't linked to what I am doing. The problem was after I realize that the driver installation was wrong I try to deinstall the driver but it would be better to revert to another snapshot on that the driver was not installed. So next time when I install a new driver and this produce failuers than I revert.
The deinstallation routine from the driver has some failures and this wrong registry entries and sys Files affect the problem. In this case the reason is long time ago and so I need the above solution to solve the problem. – May 19 '13 at 21:13.
1 Im unsure if this is technically possible as the drivers may require a different windows kernel altogether It would be great if you could come to some agreement with citrix to include the Xensource PV network drivers (if possible with standard kernel). Shadowprotect seems to works under xen, but network performance is awful (5.9 megabit network throughput) when trying to restore an image to a xen guest. I know you can load other drivers, but by the point the network is working (the only way to get access to files outside the guest OS) the network drivers are loaded as realtek drivers which work, but slowly and you dont seem to be able to replace them with the PV drivers. Im currently testing methods to migrate physical machines to Xen virtual machines, but 6 hours to restore a 140 gig compressed image is making this tedious. This is the latest shadow protect 3.1.0.3. We are a reseller and integrator of Shadowprotect and are also a Citrix XenServer partner. We see significant sales traction in the whole area of Disaster Recovery to XenServer VM but are worried about the throughput being throttled by the lack of Xen PV network drivers.
Throughput is greater when using Microsoft Virtual PC but there is more strategic reasons for selecting XenServer. An even more attractive approach would be to have a XenCentre integrated Linux / Centos utility which would restore/convert the ShadowProtect Images directly to Xen VHD volumes. I'm getting the same problem as WilliamC ie.
5MB/s network throughput whilst restoring a SP image across the network. I'm trying to restore Shadowprotect images (created with v4.01) onto Citrix XenServer 5.6 virtual disks through the Shadowprotect (4.01) recovery environment. In 2003 environment it picks up the VM NIC as Realtek and this is where i'm getting 5MB/s throughput. In the 2008 environment it's not detecting the VM NIC at all and when i try to 'Load Driver' to install the Citrix PV drivers included with XenTools it says 'Driver load completed successfully' but still doesn't appear in Network Configuration. It's just surprising that 2 years down the track there's still no default driver support for a fairly common NIC type (ie.
Citrix PV NIC. We currently are not able to support networking in the Vista/Win7 Recovery Environment on a ZenServer. The developers are aware of the issue and we have a ZenServer in house that we are using to resolve the issue. I would expect that the issue should be resolved with the release of v4.1. Atleast that is what I am being told by the development team at this time. If you are aware of any other issues that you may currently be experiencing in relation to ShadowProtect and ZenServer, please let us know so that we can investigate before the v4.1 release.
I’ve been meaning to post this on the forum, but haven’t yet had a chance to. From what I have been told, the issue is actually a driver conflict rather than a missing driver, so we do have the driver included, but when it goes to load, it is conflicting with another driver that is also being loaded. So adding the driver after the fact, does not resolve the issue. In order to resolve the issue, the Developers are currently working on a new build of the Recovery CD that will not have the driver conflict. A solution for now, would be to perform the restore minus the HIR in the Legacy/2003 environment, and then boot back into the Vista/Win7 option to perform HIR. I know this is more than just a bit of a pain, but it will work until the new build is released. I haven't been given the details of what drivers are causing the conflict.Or if it actually is another driver that is conflicting and not a conflict between the drivers and winPE itself.
I met with our head developer earlier today on the issue. We're going to be rearranging how the drivers are handled in winPE in order to resolve the conflict. We are currently looking at November for a v4.02 release. I don't have an exact date, nor can I confirm that it will be November. We were originally gunning for the end of this month, but I know of this issue and some changes to the Snapshot driver that they wanted finished before the release.

I am seeing some weird behavior in my Xen environment. I have two host servers (host1 and host2), neither of which is connected to shared storage.
On my first server, I have my XenDesktop server, domain DC for the Xen environment and a SQL server, along with a couple of dedicated and pooled VMs. On host2, I have my XenApp server and one dedicated VM. Host1 is a PowerEdge 2950, host2 is a PowerEdge 1950. My troubles started, ironically enough, on April 1. My XenDesktop site was down, so I opened XenCenter to see what was going on, and every VM on host1 was maxed-out memory-wise and would respond to no commands; VMs on host2 were fine.
Citrix For Windows 10
The only way I could shut them down was to force it. When I brought them back up, slowly their memory usage would climb until it maxed-out again. I installed Process Explorer to see if I could determine what was causing it, but no process would admit to such behavior. After much trial and error, I discovered that if I removed the Citrix Xen Windows x64 drivers from the VMs on host1, things were back to normal, with one exception.
Aerosmith discography torrent. The XenDesktop server itself isn't having any problems now. I didn't need to remove the drivers from it for it to work, even though it was one of the ones using up memory. Now, every time I uninstalled the drivers, I got the BSoD (relevant portion is attached). I even went so far as to create a new dedicated pool once I got the servers working again, which is when I added one dedicated VM each to host1 and host2. I created my Windows 7 image from scratch and used that to set up my pool.
Windows Pv Drivers
However, the same problem remains: I can't run the PV drivers on the dedicated VM on host1, but I can on host2. I am fully willing to admit that it's a server hardware problem, but a memory test and a HDD surface scan both came up clean. Am I the only one?:o.
