[libvirt] [PATCH] Fix detection of disk in IO events
When using -device syntax, the IO event will have a different prefix, 'drive-' that needs to be skipped over before matching against the libvirt disk alias * src/qemu/qemu_driver.c: Skip QEMU_DRIVE_HOST_PREFIX in IO event --- src/qemu/qemu_driver.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 3e0a38a..9434e00 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -763,6 +763,9 @@ findDomainDiskByAlias(virDomainObjPtr vm, { int i; + if (STRPREFIX(alias, QEMU_DRIVE_HOST_PREFIX)) + alias += strlen(QEMU_DRIVE_HOST_PREFIX); + for (i = 0; i < vm->def->ndisks; i++) { virDomainDiskDefPtr disk; -- 1.6.6.1
