Hi,
Does it get stuck there on:
"Mapping TX rings
0 map errors"
It doesn't show anything else?
Could you tell me your hardware specifications? and the output of these commands:
xl vcpu-list
xl info
xl dmesg
dmesg
I indeed have heard of cases where it gets stuck on mapping phase being unable to map the RX rings. But I was unable to reproduce it in my hardware.
Thanks,
Cheers,

Hi Joao,
Thanks for your prompt reply. It does get stuck at:
"Mapping TX rings
0 map errors"
and shows nothing else. The hardware specs are as follows:
CPU: Intel(R) Xeon(R) CPU E5-1607 v2 @ 3.00 GHz (4-core) (3 assigned to Dom-0)
RAM: 16 GB (with 8 GB assigned to Dom-0)
Network Card: Intel Corporation 82599 10 Gigabit TN Network Connection (dual-port)
Let me know if you require any other hardware specification.
The output to "xl vcpu-list" is:
Name ID VCPU CPU State Time(s) CPU Affinity
Domain-0 0 0 0 -b- 511.7 0
Domain-0 0 1 1 r-- 397.9 1
Domain-0 0 2 2 -b- 410.2 2
clickos 7 0 3 r-- 367.0 3
The output to "xl info" is:
Name ID VCPU CPU State Time(s) CPU Affinity
Domain-0 0 0 0 -b- 511.7 0
Domain-0 0 1 1 r-- 397.9 1

Hey Hassan,
Everything looks ok on the backend side and configurations.
Could you try booting the VM in one of the cores of Domain-0 ? For example in core 2 instead of core 3, then pinning it back to core 3.
Thanks,
Cheers
from cosmos.
HI Joao,
Great, it worked. I specified the cpu in the .cfg file and booted the VM. The console this time didn't get stuck. After that I pinned it back to core 3 by:
xl vcpu-pin clickos 0 3
Thanks a lot! Any reason why this worked?
from cosmos.
Not sure yet but will let you know when I fix the issue, in mini-os. Thanks a lot!
