    通过virsh 删除虚拟机时报错,提示cannot undefine domain with nvram,解决方法是加上--nvram


    qemuDomainUndefineFlags(virDomainPtr dom,
                            unsigned int flags)
            } else if (!(flags & VIR_DOMAIN_UNDEFINE_KEEP_NVRAM)) {
                virReportError(VIR_ERR_OPERATION_INVALID, "%s",
                               _("cannot undefine domain with nvram"));
                goto endjob;

    static bool
    cmdUndefine(vshControl *ctl, const vshCmd *cmd)
        bool nvram = vshCommandOptBool(cmd, "nvram");
        bool keep_nvram = vshCommandOptBool(cmd, "keep-nvram");

    if (nvram)
            flags |= VIR_DOMAIN_UNDEFINE_NVRAM;


    通过dump 配置文件,发现真的在配置文件中有添加

    [root@k8s-node2 ~]# virsh list
     Id    Name                           State
     25    debian6.0                      running
