I am having difficulty with a network bridge on a Win8 guest at CentOS 7
host boot.
Condition is the Win8 guest is configured to start at host boot. From a
second workstation I ping both the guest and the host. I issue a remote
reboot of the host. Both are responding to pings until the reboot.
After the reboot, the host begins to respond and shortly afterwards the
guest [sometimes] responds as well...for a time. Then I lose
connectivity with the guest. To recover, I issue a "virsh reboot
guest-name" command. Then connectivity with the guest is solid until
the host is rebooted again. Is this a "race" condition? Is it a
configuration issue? Or, is it simply a bug?
The requested information is as follows:
Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz running on an Assus MOB
qemu-kvm.x86_64 10:1.5.3-126.el7_3.5
CentOS 7.3 Linux 3.10.0-514.10.2.el7.x86_64
guest is Windows 8.1-64bit 2GB RAM, 2vcpus cpu host
Since the host cpu is exposed to the guest, the NIC defaults to the
rtl8139 type.
brctl show results:
bridge name bridge id STP enabled interfaces
br1 8000.7824af8b6272 no eno1
vnet0
virbr0 8000.525400a391c0 yes virbr0-nic
ifcfg-br1:
DEVICE="br1"
BOOTPROTO="static"
IPADDR="10.30.21.41"
NETMASK="255.255.254.0"
GATEWAY="10.30.21.1"
DNS1=10.30.21.1
ONBOOT="yes"
TYPE="Bridge"
#NM_CONTROLLED="no"
DELAY="2" #I have tried default "0" and changed to "2'" with no
improvement.
ifcfg-eno1:
DEVICE="eno1"
TYPE="Ethernet"
BOOTPROTO=none
ONBOOT=yes
#NM_CONTROLLED="no" #I have tried with/without NetworkManager
started/stopped/disabled with no improvement.
BRIDGE=br1
I would guess the following as the start command requested:
/etc/libvirt/qemu/autostart/vWIN8.xml
Again, system runs solid if I issue a virsh reboot command to the
guest. Why I need this? I have an autostart feature required of a
[internal] customer scheduled on their Win8 guest. It is network
dependent. I am unable to run it currently, because of this particular
issue. Hence, I am a slave to the Win8 guest on every host reboot. Any
suggestions? And/or point me to a forum where I may be able to get
assistance with this.
Thank you,
