This patch re-orders the initialization code to fix this problem and also makes SuspendTrigger() fail if the UNPLUG interface is not available. NOTE: The change of type of SuspendTrigger() does not require a new interface revision since it is a change from a void function to a non-void function, so older client code will simply ignore the return value.

charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: win-pv-devel-bounces@lists.xenproject.org Errors-To: win-pv-devel-bounces@lists.xenproject.org Due to a mis-ordering of the interface initialization calls in FdoCreate(), the SUSPEND interface never gets hold of the UNPLUG interface and thus, on resume from suspend, emulated device unplug is not done and the emulated network and disk devices re-appear in the VM. This patch re-orders the initialization code to fix this problem and also makes SuspendTrigger() fail if the UNPLUG interface is not available. NOTE: The change of type of SuspendTrigger() does not require a new interface revision since it is a change from a void function to a non-void function, so older client code will simply ignore the return value.

Citrix also currently arrange for Microsoft WHQL signing of XenServer PV driver releases However - none of this addresses Xen Project nightly builds which, I believe, Citrix can't vouch for (as it doesn't have control of who gets to be a project committer). Of course, if you - or anyone else - has a trusted-chain code signing certificate, there is nothing to stop you from signing the xen project driver builds yourself.

I'm hoping to get 8.0 drivers in place there soon). You can get them from the development snapshots at http://xenserver.org/open-source-virtualization-download/2-uncategorised/115-development-snapshots.html (Download the Base ISO from the snapshot list, then mount it and look inside, specifically at packages.main\tools-iso.tar.bz2\tools-iso.tar\.\opt\xensource\packages\iso\xs-tools-*.iso You'll find 2 drivers msi files (one 64 bit, one 32 bit) - you can open these with msiexec or 7zip, and extract the signed drivers from within.) Citrix also currently arrange for Microsoft WHQL signing of XenServer PV driver releases However - none of this addresses Xen Project nightly builds which, I believe, Citrix can't vouch for (as it doesn't have control of who gets to be a project committer). Of course, if you - or anyone else - has a trusted-chain code signing certificate, there is nothing to stop you from signing the xen project driver builds yourself.

charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: win-pv-devel-bounces@lists.xenproject.org Errors-To: win-pv-devel-bounces@lists.xenproject.org Any time the xenbus state transitions through XenbusStateClosed (6) then it's possible for the toolstack to tear down the vif, regardless of whether the state transition was initialiated by the backend going offline or the frontend being disabled at the same time the backend happens to go offline. It's important, therefore, that the frontend code allows for this and always requests PDO ejection if the backend does go away (even if a new immediately appears).

It's important, therefore, that the frontend code allows for this and always requests PDO ejection if the backend does go away (even if a new immediately appears).

With windows 7 freeze for some seconds instead and make me crazy trying to found the cause for 1-2 years without result :( With windows 7 temp. freeze after latest xenvif changes something is changed... after restore freeze of some seconds in qemu log show pv drivers lines from: > xen_platform_log xen platform: XENVIF|PdoRequestEject: > FFFFFA8003067540 (0) And windows popup appair showing that Xen PV Network Device #0 was removed (even if finished the second freeze network return working). Is it normal? I have setted fixed mac address in domU's xl cfg, so should not saw different netcard after save/restore FWIK qemu log (with various trace and debug active) in attachment, first freeze of some seconds was before this line: > xen_platform_log xen platform: XENVIF|PdoRequestEject: > FFFFFA8003067540 (0) And second freeze near was before this line: > xen_platform_log xen platform: XENNET|DriverEntry: XENNET 8.0.0 (18) > (24.03.2015) And third freeze after xl shutdown and before this line: > xen_platform_log xen platform: XEN|SystemPowerStateCallback: <- S0 Is there a way to know if there are unexpected case in pv drivers on restore that can cause the freeze or not?

With windows 7 freeze for some seconds instead and make me crazy trying to found the cause for 1-2 years without result :( With windows 7 temp. freeze after latest xenvif changes something is changed... after restore freeze of some seconds in qemu log show pv drivers lines from: > xen_platform_log xen platform: XENVIF|PdoRequestEject: > FFFFFA8003067540 (0) And windows popup appair showing that Xen PV Network Device #0 was removed (even if finished the second freeze network return working). Is it normal? I have setted fixed mac address in domU's xl cfg, so should not saw different netcard after save/restore FWIK qemu log (with various trace and debug active) in attachment, first freeze of some seconds was before this line: > xen_platform_log xen platform: XENVIF|PdoRequestEject: > FFFFFA8003067540 (0) And second freeze near was before this line: > xen_platform_log xen platform: XENNET|DriverEntry: XENNET 8.0.0 (18) > (24.03.2015) And third freeze after xl shutdown and before this line: > xen_platform_log xen platform: XEN|SystemPowerStateCallback: <- S0 Is there a way to know if there are unexpected case in pv drivers on restore that can cause the freeze or not?

Hello,

I have an existing= guest VM of windows 2008 server running on Xen windows GplPv drivers. I am= looking for any guidance document on how to replace these drivers with the= new PV drivers.

Basically, I need to use xeniface driver to c= ommunicate with xenstore.

On a different note, is xenifac= e driver compatible with the Xen GplPv drivers?

Hello,

I have an existing= guest VM of windows 2008 server running on Xen windows GplPv drivers. I am= looking for any guidance document on how to replace these drivers with the= new PV drivers.

Basically, I need to use xeniface driver to c= ommunicate with xenstore.

On a different note, is xenifac= e driver compatible with the Xen GplPv drivers?

Hello,

I have an existing guest VM of windows 2008 server running on Xen windows GplPv drivers. I am looking for any guidance document on how to replace these drivers with the new PV drivers.

Basically, I need to use xeniface driver to communicate with xenstore.

On a different note, is xeniface driver compatible with the Xen GplPv drivers?

You must remove the old gplpv with its uninstall from control panel and uninstall_0.10.x.bat (from old gplpv site, needed for don't have blue screen after reboot), reboot windows and after install new winpv.

Hello,

I have an existing guest VM of windows 2008 server running on Xen windows GplPv drivers. I am looking for any guidance document on how to replace these drivers with the new PV drivers.

Basically, I need to use xeniface driver to communicate with xenstore.

On a different note, is xeniface driver compatible with the Xen GplPv drivers?

You must remove the old gplpv with its uninstall from control panel and uninstall_0.10.x.bat (from old gplpv site, needed for don't have blue screen after reboot), reboot windows and after install new winpv.

Do you know if the guest vcpus are busy during the freeze?

Where I can find an howto for do more useful debugging for this case?
