...hould just work to minimize upgrade efforts. http://lxr.xensource.com/lxr/source/tools/blktap2/README also still mention tap:tapdisk, and not tap2:tapdisk. Second problem, using that combination, blktap2 devices was not cleanly freed. /sys/class/blktap2/devices and tapdisk devices keep increasing (tapdev0, tapdev1, etc.). The strange thing is, when using Xen 4.0.1 hypervisor but with Xen 4.0.0 userland, tap:tapdisk and blktap2 device cleanup works as expected. -- Fajar _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/x...

Hi, Currently i''m going through the source codes of tools/blktap2. I need to find-out where blktap2 calls 1. mem_share_nominate() 2. mem_sharing_share_page() functions to do the memory sharing on HVM guests. Can someone please provide me some guidance on blktap2 driver. Thanks, Harshan _______________________________________________ Xen-devel mailing list

Ok running Kubuntu 11.04, is it possible to get XEN 4.1 installed to virtual a laptop running Kubuntu ? I seriously dont want to use Vbox or KVM, and need to run other OS for development, so XEN virtualization on a 8 core laptop with 16 gig memory seem the best bet for mobile development _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The
