[libvirt] [PATCH REPOST 2/8] qemu: Introduce qemuBuildSerialCommandLine

Add new function to manage adding the serial device options to the command line removing that task from the mainline qemuBuildCommandLine. Using const virDomainDef causes collateral damage in other called APIs which need to make the similar adjustment Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- src/qemu/qemu_capabilities.c | 2 +- src/qemu/qemu_capabilities.h | 2 +- src/qemu/qemu_command.c | 114 ++++++++++++++++++++++++------------------- src/qemu/qemu_command.h | 2 +- 4 files changed, 67 insertions(+), 53 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 403d872..b223837 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -3839,7 +3839,7 @@ virQEMUCapsCacheFree(virQEMUCapsCachePtr cache) bool -virQEMUCapsSupportsChardev(virDomainDefPtr def, +virQEMUCapsSupportsChardev(const virDomainDef *def, virQEMUCapsPtr qemuCaps, virDomainChrDefPtr chr) { diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index 01ceb8e..caf3d1b 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -450,7 +450,7 @@ int virQEMUCapsParseDeviceStr(virQEMUCapsPtr qemuCaps, const char *str);
