The RPC limits for cpu maps didn't allow to use libvirt on ultra big boxes. This patch increases size of the limits to support a maximum of 16384 cpus on the host with a maximum of 4096 cpus per guest. The full cpu map of such a system takes 8 megabytes and the map for vcpu pinning is 2 kilobytes long. --- src/remote/remote_protocol.x | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/remote/remote_protocol.x b/src/remote/remote_protocol.x index 1ebbce7..9723377 100644 --- a/src/remote/remote_protocol.x +++ b/src/remote/remote_protocol.x @@ -82,13 +82,13 @@ const REMOTE_DOMAIN_ID_LIST_MAX = 16384; const REMOTE_DOMAIN_NAME_LIST_MAX = 16384; /* Upper limit on cpumap (bytes) passed to virDomainPinVcpu. */ -const REMOTE_CPUMAP_MAX = 256; +const REMOTE_CPUMAP_MAX = 2048; /* Upper limit on number of info fields returned by virDomainGetVcpus. */ -const REMOTE_VCPUINFO_MAX = 2048; +const REMOTE_VCPUINFO_MAX = 16384; /* Upper limit on cpumaps (bytes) passed to virDomainGetVcpus. */ -const REMOTE_CPUMAPS_MAX = 16384; +const REMOTE_CPUMAPS_MAX = 8388608; /* Upper limit on migrate cookie. */ const REMOTE_MIGRATE_COOKIE_MAX = 16384;
