Hi All ,
I am using xen 3.2.0 which i have built form source ,I could
initially boot Dom 0 and some DomUs.
But today when i tried to boot a DomU with birdge enabled it
didnt work giving an error ....
Error: Device 0 (vif) could not be connected. Hotplug scripts
not working.
After that I checked my var/log/messages and It gave lots of
xenstore-write segfault,exact error is attached iniline.
Jul 12 07:26:46 centosxcat2 kernel: xenstore-read[16643]: segfault at
0000000000000000 rip 0000000000000000 rsp 00007fff2036def8 error 4
Now I dont know whether segfault error were caused by first
error or they are independent , I think they occured after
i tried to create domU with bridge networking.
And also this error (segfault) is occurring continuously
without stop and filling up the var/log/messages.
Can someone explain why is these errors are coming ?
And how can I remove them ...
Domu config file
kernel = "/boot/vmlinuz-2.6.18.8-xenU"
ramdisk = "/boot/initrd-2.6.18.8-xenU.img"
memory = 256
name = "u2"
vif = [ '''', ''bridge=xenbr1'' ]
root = "/dev/sda2"
extra = "4"
/var/log/xen/xen-hotplug.log contains continious line like these (It
is 1GB file ) (last line is interesting)
