Re: [libvirt] [PATCH v4 7/7] qemu: Add ability to abort existing console while creating new one

This patch fixes console corruption, that happens if two concurrent sessions are opened for a single console on a domain. Result of this corruption was that each of the console streams recieved just a part

of the data written to the pipe so every console rendered unusable. New helper function for safe console handling is used to establish the console stream connection. This function ensures that no other libvirt client is using the console (with the ability to disconnect consoles of libvirt clients) and that no UUCP style lockfile is placed on the PTY device. * src/qemu/qemu_domain.h - add data structure to domain's private data dealing with console connections * src/qemu/qemu_domain.c: - allocate/free domain's console data structure * src/qemu/qemu_driver.c - use the new helper function for console handling --- src/qemu/qemu_domain.c | 5 +++++ src/qemu/qemu_domain.h | 3 +++ src/qemu/qemu_driver.c | 21 ++++++++++++++++----- 3 files changed, 24 insertions(+), 5 deletions(-)
