Hello,
Ian: Any idea what could cause this error message (more info below):
"XENBUS: Timeout connecting to device: device/vif/0 (state 1)"
Is this from the domU or the dom0?
This is from the domU.
Do other devices work ok?
Yes, everything else seems to be working fine.
User says replacing 2.6.38/2.6.39 pvops dom0 kernel with xenlinux one
fixes the problem..
2.6.38 didn't have netback, only 2.6.39-rc1 did. Mario, please can you
supply the .config you used with the 2.6.39 kernel and the exact commit
id you are using. It would also be useful to see a complete log from
both dom0 and domU.
Pvops kernel configs are here:
http://dev.slackverse.org/tmp/config-2.6.39-rc7-xen
http://dev.slackverse.org/tmp/config-2.6.37.6-xenU
They are both based on default configs shipped with Slackware, with
minimal xen-only options enabled.
Well, when i saw that 2.6.39-rc7 did not work, and i did not expect
anyone to care, i simply wiped all of the pvops stuff that i was
testing, and replaced it with a gentoo patched kernel wich works.
If it will not be in vain, i will compile it again and give you more
details.
Yes please, we care very much about pvops to working well for everyone.
(I'm not sure why you would think otherwise, this has been the focus of
our development efforts for several years now).
Ian.
Fair enough, it is compiling as we speak. Report to follow shortly.
m.
Do the vif entries appear in XenStore? Using:
xenstore-ls /local/domain/$(xl domid<name>)/devices/vif
you should see some entries and those entries should reference a
backend
path which should also contains entries, please post both.

Hope it helps, i might not be able to power this box on any more, but if
you need something else i will keep the drives and boot them up in
another server on your request..

Well, from what i remember, only vhd was being shown, but i will try and
get you exact info today.

Hey everyone,
I have been trying to make Xen-4.1.0 work on kernels
mentioned in the
subject, without much sucess. HVM guests are not
affected, only PV.
Below you mention gentoo xenlinux patches..
So please be more specific about which kernel was vanilla
(pvops),
and which kernels had some external patches applied..
-- Pasi
Sorry, both kernels in subject were vanilla from
kernel.org, with xen
options selected for dom0 usage.
I only wanted to point out that networking works if i use
kernel patched
with rebased gentoo patches.
I am talking only about dom0 kernel here, domU kernel does
not seem to
be the source of the problem.
OK. What kernel is the PV domU running? What Xen version are
you using? 4.1 ?
-- Pasi
Well, i have tried following kernels in domU:
2.6.31.6 (i got this one from stacklet)
2.6.37.6-domU
2.6.33.4-domU
Are these pvops/vanilla or with some patches?
Those are pvops/vanilla, no patches.
2.6.38.6-xen (dom0 kernel)
2.6.34.7-xen (dom0 kernel)
2.6.39-rc7-xen (dom0 kernel)
None of them made any difference, they were all complaining
about vif.
Yeah, I am running Xen 4.1
Are you using xm/xend or xl/libxl toolstack?
I am using xl/libxl with Xen 4.1
Ok. Have you tried Jeremy's xen.git xen/stable-2.6.32.x as a
dom0 kernel?
It would be interesting to know if that works for you or not.
Btw. Did you realize upstream 2.6.38 / 2.6.39 does not yet have
xen-blkback driver included? also blktap2 driver is missing.
So you you can only use the phy: or file: backends, assuming Xen
4.1,
which has the (slow) fallback qemu-based userspace blkback
implementation.
-- Pasi
Yes i have, but seeing that HVM networking works, i wanted to
report the
PV one that doesn't.
m.
Error that i see in dmesg on the domU:
XENBUS: Timeout connecting to device: device/vif/0 (state 1)
ifconfig -a on domU shows MAC address: 00:00:00:00:00:00
dom0 doesn't have any vif/tap interfaces assigned to domU
when i do
brctl show or ifconfig -a
I don't see any errors worth mentioning in /var/log/xen,
except mybe
these two:
/tmp/SBo/xen-4.1.0/tools/ioemu-qemu-xen/hw/xen_blktap.c:628:
Init blktap
pipes
Could not open /var/run/tap/qemu-read-2
Problem goes away when i boot 2.6.34.7 (it is the last
kernel that i
have built with gentoo rebased patches).
If there is something i can do to help debug this please
do let me know.
Best regards,
mario
