Re: [libvirt] [PATCH 05/12] qemu: Manage disk's unpriv_sgio in domain lifecyle

Here lifecyle only means starting and shutdown. To record the original "unpriv_sgio" value for non-shared disk, this introduces "orig_cdbfilter" for disk def. On domain starting, the disk's "unpriv_sgio" is set with regards to the config in domain XML. And on domain shutdown, it's restored to the original value ("orig_cdbfilter"). Later patch will prevent restoring if other domain is still using the shared disk. --- src/conf/domain_conf.h | 1 + src/qemu/qemu_process.c | 34 +++++++++++++++++++++++++++++++++- 2 files changed, 34 insertions(+), 1 deletions(-) diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 9586f75..256bea2 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -629,6 +629,7 @@ struct _virDomainDiskDef { bool rawio_specified; int rawio; /* no = 0, yes = 1 */ int cdbfilter; + int orig_cdbfilter;
