Re: [Libvir] [PATCH] check the maximum of virtual CPU

Hi The maximum of virtual CPU is not guarded in virsh setvcpus now. Then, when 32767 was set to virtual CPU of virsh setvcpus, the problem that Xend became abnormal was detected. example: ---------------------------------------------------------------------- # virsh setvcpus 0 32767 libvir: Xen Daemon error : POST operation failed: (xend.err "(9, 'Bad file descriptor')") libvir: Xen error : failed Xen syscall ioctl 3166208 libvir: error : library call virDomainSetVcpus failed, possibly not supported # xm list -l Error: (9, 'Bad file descriptor') Usage: xm list [options] [Domain, ...] List information about all/some domains. -l, --long Output all VM details in SXP --label Include security labels --state=<state> Select only VMs with the specified state ---------------------------------------------------------------------- Therefore, I propose the correction that adjusts the maximum of virtual CPU to the same value as Xen. This patch is over 200lines. If you request, I am ready to repost it with split this patch.
