Re: [libvirt] [PATCH 1/4] vcpupin: inroduce a new libvir API (virDomainPinVcpuFlags)

This patch introduces a new libvirt API (virDomainPinVcpuFlags) Signed-off-by: Taku Izumi <izumi.taku(a)jp.fujitsu.com&gt;

/** + * virDomainPinVcpuFlags: + * @domain: pointer to domain object, or NULL for Domain0 + * @vcpu: virtual CPU number + * @cpumap: pointer to a bit map of real CPUs (in 8-bit bytes) (IN) + * Each bit set to 1 means that correspoinding CPU is usable.

+ * Bytes are stored in little-endian order: CPU0-7, 8-15... + * In each byte, lowest CPU number is least significant bit. + * @maplen: number of bytes in cpumap, from 1 up to size of CPU map in + * underlying virtualization system (Xen...). + * If maplen < size, missing bytes are set to zero. + * If maplen < size, failure code is returned.

+ * @flags: an OR'ed set of virDomainVcpuFlags

+ * + * Dynamically change the real CPUs which can be allocated to a virtual CPU. + * This function requires privileged access to the hypervisor. + * + * @flags must include VIR_DOMAIN_VCPU_LIVE to affect a running domain + * (which may fail if domain is not active), or VIR_DOMAIN_MEM_CONFIG to

+ * affect the next boot via the XML description of the domain. + * Both flags may be set. + * + * Returns 0 in case of success, -1 in case of failure. + * + */ +int +virDomainPinVcpuFlags(virDomainPtr domain, unsigned int vcpu, + unsigned char *cpumap, int maplen, unsigned int flags) +{ Index: libvirt/src/libvirt_public.syms =================================================================== --- libvirt.orig/src/libvirt_public.syms +++ libvirt/src/libvirt_public.syms @@ -434,6 +434,7 @@ LIBVIRT_0.9.0 { virEventRunDefaultImpl; virStorageVolDownload; virStorageVolUpload; + virDomainPinVcpuFlags; } LIBVIRT_0.8.8;
