According to an example, in a method for redirecting virtual machine traffic a virtual switch may be implemented in a physical server. In addition, a packet sent from a first virtual machine to a second virtual machine may be detected, in which the first virtual machine and the second virtual machine are in the same virtual local area network (VLAN), and in which the packet has a first VLAN label that identifies the VLAN. Moreover, the first VLAN label may be replaced with a second VLAN label in the packet, in which the second VLAN label differs from the first VLAN label, and the packet may be sent to an uplink switch, in which the uplink switch may send the packet to a network security module.

Redirecting virtual machine traffic

According to an example, a service coordination apparatus may include a processor that is to determine whether each GLB node-pair in a node-pair state table is at a normal state after receiving a DNS request. If a GLB node-pair in the node-pair state table is not at the normal state, a second DNS response may be sent to a node sending the DNS request according to a DNS parsing list. If each GLB node-pair in the node-pair state table is at the normal state, a proximity list may be inquired. If a record corresponding to the DNS request is searched out from the proximity list, a first DNS response may be sent to the node sending the DNS request according to the searched out record. If not, a second DNS response may be sent to the node sending the DNS request according to the DNS parsing list.
