Re: [libvirt] [PATCH 6/7] qemu: use lighter-weight fd:n on incoming tunneled migration

Outgoing migration still has to use a Unix socket and or exec netcat, since there is no way to pass a migration fd into qemu via monitor commands, but incoming migration need not suffer from the complexity. * src/qemu/qemu_driver.c (qemudDomainMigratePrepareTunnel): Replace Unix socket with simpler pipe. Suggested by Paolo Bonzini. --- I've since been corrected; qemu_monitor.c has qemuMonitorIOWriteWithFD that looks like it can be used to avoid exec: on outgoing migrations by instead passing an open fd over a unix socket, although I have not tested that yet. However, this patch does not need to be held up by waiting for the followup patch that optimizes outgoing migrations. src/qemu/qemu_driver.c | 49 +++++++++++++++-------------------------------- 1 files changed, 16 insertions(+), 33 deletions(-)
