2009-02-05toplevel: remove error handling from qemu_malloc() callers (Avi Kivity)aliguori1-2/+0
Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6531 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-12Fix brown-paper-bag bugs from live-migration patch (Charles Duffy)aliguori1-1/+1
In TCP migration, prevent an endless loop trying to retrieve error status. In exec migration, set the close pointer in the FdMigrationState structure. Color me embarrassed.

2008-11-11Reintroduce migrate-to-exec: support (Charles Duffy)aliguori1-170/+18
KVM's live migration support included support for exec: URLs, allowing system state to be written or received via an arbitrary popen()ed subprocess. This provides a convenient way to pipe state through a compression algorithm or an arbitrary network transport on its way to its destination, and a convenient way to write state to disk; libvirt's qemu driver currently uses migration to exec: targets for this latter purpose. This version of the patch refactors now-common code from migrate-tcp.c into migrate.c.

2008-10-24Live migration for Win32 (Hervé Poussineau)aliguori1-11/+11
This patch fixes migration so that it works on Win32. This requires using socket specific calls since sockets cannot be treated like file descriptors on win32.

2008-10-24Fix windows build after migration changesaliguori1-2/+2
The live migration code broke the windows build. As part of this change, I've switched the BIOS path to C:\Program Files\Qemu instead of /c/Program Files/Qemu. The later is only valid when launching from MSYS but the former is always valid.

2008-10-13Introduce TCP live migration protocolaliguori1-0/+371
This patch introduces a tcp protocol for live migration. It can be used as follows: qemu-system-x86_64 -hda ~/images/linux-test.img -monitor stdio <vm runs for a while> (qemu) migrate tcp:localhost:1025 On the same system: qemu-system-x86_64 -hda ~/images/linux-test.img -incoming tcp:localhost:1025 The monitor can be interacted with while waiting for an incoming live migration.
