From 5903378834bafb031407ab02ce37dcc9ec782d1f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A1n=20Tomko?= Date: Mon, 2 Mar 2015 10:58:48 +0100 Subject: [PATCH] Allocate virtio-serial addresses when starting a domain Instead of always using controller 0 and incrementing port number, respect the maximum port numbers of controllers and use all of them. Ports for virtio consoles are quietly reserved, but not formatted (neither in XML nor on QEMU command line). Also rejects duplicate virtio-serial addresses. https://bugzilla.redhat.com/show_bug.cgi?id=890606 https://bugzilla.redhat.com/show_bug.cgi?id=1076708 Test changes: * virtio-auto.args Filling out the port when just the controller is specified. switched from using maxport + 1 to: first free port on the controller * virtio-autoassign.args Filling out the address when no
is specified. Started using all the controllers instead of 0, also discards the bus value. * xml -> xml output of virtio-auto The port assignment is no longer done as a part of XML parsing, so the unspecified values stay 0. --- src/conf/domain_conf.c | 48 +++++--------- src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 1 + src/qemu/qemu_command.c | 63 +++++++++++++++++++ src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain.h | 1 + src/qemu/qemu_process.c | 2 + .../qemuxml2argv-channel-virtio-auto.args | 2 +- ...emuxml2argv-channel-virtio-autoassign.args | 10 +-- .../qemuxml2xmlout-channel-virtio-auto.xml | 9 ++- 10 files changed, 93 insertions(+), 45 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 4e5c538a3f..1763305e64 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -3512,21 +3512,6 @@ virDomainDeviceDefPostParseInternal(virDomainDeviceDefPtr dev, chr->target.port = maxport + 1;
