Debian KVM virtual machine encounter card flash off the problem for help!

I am a novice just contact KVM, met card flash problem when using KVM
My system: 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1+deb7u1 x86_64 GNU/Linux
KVM version: QEMU emulator version 1.1.2 (qemu-kvm-1.1.2+dfsg-6, Debian), Copyright (c) 2003-2008 Fabrice Bellard
Virtual machine card types: default

In this environment, the same physical machine after multiple virtual machines, virtual serial opportunity card flash off, and from the current situation, the virtual machine problem is fixed, /var/log/messages information is as follows
Nov 6 14:09:15 kernel: [3704373.326856] 8139cp 0000:00:07.0: eth1: link up, 100Mbps, full-duplex, lpa 0x05E1
Nov 6 14:10:05 kernel: [3704422.801102] 8139cp 0000:00:07.0: eth1: link up, 100Mbps, full-duplex, lpa 0x05E1


According to the error information online inquiry and ask others, said to be 8139 card too old, there are said to be KVM 8139 bug card virtual existence, so put a virtual network card type to E1000, but the machine is still had a flash, /var/log/messages information is as follows:
Nov 7 06:07:16 kernel: [58400.573083] ADDRCONF(NETDEV_UP): eth1: link is not ready
Nov 7 06:07:18 kernel: [58402.572751] e1000: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
Nov 7 06:07:18 kernel: [58402.574819] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
Nov 7 06:08:05 kernel: [58450.085420] ADDRCONF(NETDEV_UP): eth1: link is not ready
Nov 7 06:08:07 kernel: [58452.084714] e1000: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
Nov 7 06:08:07 kernel: [58452.086555] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready


The flash with frequency variable, sometimes a continuous flash off, sometimes several or even dozens of hours once, when flashing occurred, from the machine to the Ping is "network unreachable".

Now no what method, everybody has what good solutions or ideas? Thank you!

Oh then whether to solve this problem.

No, later or by VMWare. If extensive use, recommend the use of OVM.
