Re: [PATCH] lib: Prohibit parallel connections with tunneled migration

As discussed on the developer list, parallel migration connections are not compatible with tunneled migration https://www.redhat.com/archives/libvir-list/2020-January/msg00463.html Prohibit the concurrent use of parallel and tunneled migration options. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com&gt; --- I added the check to all migration entry points except virDomainMigrate3, where the p2p and tunneled options are already prohibitied. src/libvirt-domain.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/src/libvirt-domain.c b/src/libvirt-domain.c index 4074397b30..b910ba6b4d 100644 --- a/src/libvirt-domain.c +++ b/src/libvirt-domain.c @@ -3546,6 +3546,10 @@ virDomainMigrate(virDomainPtr domain, VIR_MIGRATE_NON_SHARED_INC, error); + VIR_EXCLUSIVE_FLAGS_GOTO(VIR_MIGRATE_TUNNELLED, + VIR_MIGRATE_PARALLEL, + error); + if (flags & VIR_MIGRATE_OFFLINE) { if (!VIR_DRV_SUPPORTS_FEATURE(domain->conn->driver, domain->conn, VIR_DRV_FEATURE_MIGRATION_OFFLINE)) { @@ -3701,6 +3705,10 @@ virDomainMigrate2(virDomainPtr domain, VIR_MIGRATE_NON_SHARED_INC, error); + VIR_EXCLUSIVE_FLAGS_GOTO(VIR_MIGRATE_TUNNELLED, + VIR_MIGRATE_PARALLEL, + error); + if (flags & VIR_MIGRATE_OFFLINE) { if (!VIR_DRV_SUPPORTS_FEATURE(domain->conn->driver, domain->conn, VIR_DRV_FEATURE_MIGRATION_OFFLINE)) { @@ -4087,6 +4095,10 @@ virDomainMigrateToURI(virDomainPtr domain, virCheckReadOnlyGoto(domain->conn->flags, error); virCheckNonNullArgGoto(duri, error); + VIR_EXCLUSIVE_FLAGS_GOTO(VIR_MIGRATE_TUNNELLED, + VIR_MIGRATE_PARALLEL, + error); + if (virDomainMigrateUnmanagedCheckCompat(domain, flags) < 0) goto error; @@ -4159,6 +4171,10 @@ virDomainMigrateToURI2(virDomainPtr domain, virCheckDomainReturn(domain, -1); virCheckReadOnlyGoto(domain->conn->flags, error); + VIR_EXCLUSIVE_FLAGS_GOTO(VIR_MIGRATE_TUNNELLED, + VIR_MIGRATE_PARALLEL, + error); + if (virDomainMigrateUnmanagedCheckCompat(domain, flags) < 0) goto error; @@ -4232,6 +4248,10 @@ virDomainMigrateToURI3(virDomainPtr domain, virCheckDomainReturn(domain, -1); virCheckReadOnlyGoto(domain->conn->flags, error); + VIR_EXCLUSIVE_FLAGS_GOTO(VIR_MIGRATE_TUNNELLED, + VIR_MIGRATE_PARALLEL, + error); + if (virDomainMigrateUnmanagedCheckCompat(domain, flags) < 0) goto error;
