Hello again.
I'm currently testing xen 3.2 package released with mandriva 2008.1.
However, I can't reuse my existing xen 3.1 HVM or PVM guest, nor install
new HVM guests...
I just updated to 3.2.1, the problem persists.
I'm joining console output, and xend log, when launching a PV host. I'm
using the same kernel (linux-hg-2.6.18), for dom0 and domU.
xm list show the host is in b state:
[root@baobab xen]# xm list
Name ID Mem VCPUs State
Time(s)
Domain-0 0 7514 4 r-----
128.3
test 1 512 1 -b----
2.9
According to the process table, xenconsole is apparently the parent of a
defunt python process.
root 8442 0.0 0.0 20552 636 pts/0 Sl+ 12:10 0:00 |
\_ /usr/lib64/xen/bin/xenconsole 1
root 8443 0.0 0.0 0 0 pts/0 Z+ 12:10 0:00 |
\_ [python] <defunct>
And strace shows process 8442 hanging on read call:
[root@baobab xen]# strace -f -p 8442
Process 8548 attached with 2 threads - interrupt to quit
[pid 8442] select(7, [0 4 6], NULL, NULL, NULL <unfinished ...>
[pid 8548] read(3,
Any hint or other trace I could attempt ?
