I want to add some parameters when vm is migrated. As I can see , vmm will use xc_domain_save(tools\libxc\Xc_domain_save.c) function ,and the main function of xc_save.c is responsible for inputting parameters. so I just want to know which function will use this executable file.

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 modifying this two binaries, recompile them with "make tools" and then copy them into /usr/lib64/xen/bin/ . However, after doing this, when running the...

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 co...

Trying to migrate a 64bit PV guest with 64GB running medium to heavy load on xen 3.4.0, it is showing lot of soft lockups. The softlockups are causing dom0 reboot by the cluster FS. The hardware has 256GB and 32 CPUs. Looking into the hypervisor thru kdb, I see one cpu in sh_resync_all() while all other 31 appear spinning on the shadow_lock. I vaguely remember seeing some thread on this while
