vxlan network dvr baremetal floating ip

虚机绑定floating ip,外出流量到qrouter namespace做SNAT,再根据ip rule查路由到fip namespace,在fip namespace配置一条路由,开启proxy_arp baremetal port没有绑定的hostid,LBaas中的vip有可能漂移,也没有绑定的host_id,它是怎么绑定floating ip的。 那么只要允许neutron中给vnic_type=baremetal的port绑定floating ip,再在ironic创建baremetal时update_port时把host_id设置为空,那么就可以给 baremetal绑定floating ip了,试一下还真可以。???? 总结一下,openstack原生不能给baremetal绑定floating ip,只要两点很小的修改就可以实现了,但不知道有没有什么风险?欢迎留言指出。

    验证C程序的高效浮点位爆破API(CS LO)

    For the evaluation, we compared our floating-point API against the native floating-point APIs in Z3 and We show that Boolector, when using floating-point API, outperforms the solvers with native support for floating-points, correctly verifying more programs in less time. Experimental results also show that our floating-point API implemented in ESBMC is on par with other Furthermore, when verifying programs with floating-point arithmetic, our new floating-point API produced

    neutron外网支持多子网

    ip,一个虚拟机绑定了floating ip,没有绑定floating ip的虚拟机访问另一个虚拟机的floating ip,那么流量在snat查路由到了计算节点的fip中。 ip热迁移,只要fg口开启proxy_arp功能,即使floating ip和fg口配置的ip不在同一个subnet,因为在同一个vlan下,也能收到arp请求,也会进行arp应答。 第二个问题,绑定floating ip的虚拟机访问其它虚拟机的floating ip,流量在fip中的ip rule发给网关,网关查路由再绕回来,需要加ip rule让查main表,不要绕网关。 4.router1绑定外网,router2绑定外网,给vm1,vm2和vm4绑定floating ip,fip中ip rule和route table正确,虚拟能通过fip访问外网,解绑定floating 5.给外网增加一个子网,给vm3给新子网中分配一个floating ip,fip中新加了subnet对应的东西,vm3解绑定floating ip,fg口ip保留。
