Cédric Le Goater 75d7150c63 s390x/pv: Implement a CGS check helper ... When a protected VM is started with the maximum number of CPUs (248), the service call providing information on the CPUs requires more buffer space than allocated and QEMU disgracefully aborts : LOADPARM=[........] Using virtio-blk. Using SCSI scheme. ................................................................................... qemu-system-s390x: KVM_S390_MEM_OP failed: Argument list too long When protected virtualization is initialized, compute the maximum number of vCPUs supported by the machine and return useful information to the user before the machine starts in case of error.
