There is a race condition between XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY and HVMOP_track_dirty_vram hypercall. Although HVMOP_track_dirty_vram is called many times from qemu-dm which is connected via VNC, XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY is called only once from a migration process (e.g. xc_save, libxl-save-helper). So the race seldom happens, but the following cases are possible.

Hello everyone, for research purposes I''m working on Xen 3.0.3 and trying to make some modifications to Xen migration. By looking at the documentation, I''ve learned that the part I''m interesting in are handled by two binaries (xc_save and xc_restore), so I thought about modifying just this two binaries instead of recompiling the whole Xen everytime, so what I do is just

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 first of all, thank you for a great project i really enjoy! ok, now here comes the bug report... i''m trying to test xen migration capabilities, with xen-3.1, hand compilled, fetched from mercurial repository. my setup looks like this - x86_64 dom0, x86_32p dom0, x86_32p domU. when trying to migrate from 64 to 32 bit dom0 i''m

Hi all! I have installed xen on fc6 with kernel 2.6.18-1.2798.fc6xen with rpm package; i have create 3 guest os (fully virtualization) with virt-manager tool, installed on separated partition: 1 fc6 guest, 1 centos 4.4, 1 windows xp pro; all work pretty fine until this point, i have linked the configuration file of the guests machines to /etc/xen/auto for autostart/autostop, but when

Hi... I have some difficulty to migrate a VM with Windows 2003 Server installed... I have two servers with DRBD as a Storage Server between this both servers.

Dear all: I am trying to migrate a WinXP HVM (64M memory) from a machine (sender) to another machine (receiver) through AoE disk, however, there are some errors when do the following command: (My xen version is xen-4.0.1-rc5.hg, kernel 2.6.31.13, xen xen-4.0.1-rc6-pre, Both sender and receiver are the same xen version) xm migrate --live domain_id receiver_ip

Hi all, I need to make some modifications to xc_save and xc_restore to Xen 3.0.3 for research purposes. In order to avoid to recompile all the xen source at each modification I do to these binaries, I thougt to substitute the version of this two binaries which is installed in /usr/lib64/xen/bin, with a version I compile myself from the Xen source code tarball. The problem is that after doing

hi, I have 2 servers running xen 3.2 on ubuntu 8.0.4.1 (64-bit) installed from the repositories (2.6.24-22-xen) with Intel-Quadcore CPU''s. The setup is based on http://www.asplund.nu/xencluster/xen-cluster-howto.html. I can start the domU (ubuntu 8.0.4.1 (64-bit)) on each server without problems. But when I start the live-migration with xm migrate dummy xen2 --live the migration

Hello, When I snapshot a vm( hvm centos ) the first time, it succeed. There is a snapshot file on disk and the vm is running. But when I do it the second time, it fail for timeout. what''s wrong with it? This error happened when I used xen-4.0.1-rc5 and kernel-2.6.31.13. Today I update to xen-4.0.1 and kernel-2.6.32.25, it is with the same wrong. Error message:

Just wondering if this is a known bug? Trying to migrate the VM off to a diff dom0 results in the below error. Other VMs migrated off fine (started at around the same time as this vm) and I''ve tried a few different target servers, all resulting in the same thing.

The VMI ROM has a mode where hypercalls can be queued and batched. This turns out to be a significant win during context switch, but must be done at a specific point before side effects to CPU state are visible to subsequent instructions. This is similar to the MMU batching hooks already provided. The same hooks could be used by the Xen backend to implement a context switch multicall. To

Hi, I implemented my own Hypercall in xen. Now I wish my application under dom0 could talk to Xen via my hypercall. Currently, I make a stub in dom0''s kernel, which works as a proxy to forward the request. So, my application first makes a system call to dom0, which then makes hypercall to xen. Is this design necessary? May I call hypercalls from user application under dom0 directly?
