[CentOS-virt] Device 0 (vif) could not be connected. Hotplug scripts not working.
Hi,
I got this error when starting a domU on Centos 5.1 i386,
Device 0 (vif) could not be connected. Hotplug scripts not working.
Why is this happening ? I should restart the machine to see if this
still happends after a fresh network bridge. But it's somehow a
production server, I would like not to restart it, if possible. No domU
is currently running. I could start domUs a week ago.
Here are the troubbleshooting information I have (everything seems fine),
- Centos 5.1 xen-3.0.3 and kernel 2.6.18-53
- ifconfig -a shows,
eth0, lo, peth0, sit0, veth1, veth2, veth3, vif0.0, vif0.1, vif0.2,
vid0.3 and xenbr0.
- brctl show,
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no peth0
vif0.0
- activated/deactivating iptables doesn't change anything. Note,
securitylevel and SELinux are disabled. Currently deactivated,
Chain INPUT (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)

issue, not vbd),

Note, someone reported the bug on RHEL5 x86_64; I guess I shouldn't add
a command as a CentOS user (not mentioning I doubt I could reproduce the
bug), https://bugzilla.redhat.com/show_bug.cgi?id=408901
Anthing I could do to dig some more ? How to fix this ? I can't play
around so much on this server, although I already restarted udev and
haldaemon, no changes. (I might reboot it some day but the problem may
disapear then, after a fresh reboot).
Thanks

[CentOS-virt] Re: Device 0 (vif) could not be connected. Hotplug scripts not working.
Here's the VM's config file which I forgot,
name = "xmb"
memory = "256"
disk = ['tap:aio:/data/xmb/xmb.ext3,xvda1,w',\
'tap:aio:/data/xmb/xmb.swap,xvda2,w']
vif = [ 'bridge=xenbr0' ]
kernel = "/data/xmb/vmlinuz"
ramdisk = "/data/xmb/initrd"
extra = "init=/bin/sh"
root = "/dev/xvda1"
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'
Note.
- I also tryed with file:...hda... (which the last email's provided logs
were about) instead of tap:aio:...xvda
- I tryed with nonspars too, no changes (vif error anyways, not vbd)
- Forcing vif's mac address doesn't help either.
- Don't bother about the use of partitions instead of a whole virtual
disk (this usually works great you know that;)).
Thanks
