xend crashes at startup with following stack trace:
...
File "/usr/lib64/python/xen/xend/XendPIF.py", line 68, in
linux_get_phy_ifaces
phy_ifaces.append((name, int(mtu), bridged_mac))
UnboundLocalError: local variable 'bridged_mac' referenced before assignment
The simple patch attached below prevent the crash, and allow xend to
start normally.
It seems the crash happens when bridged_ifname is set to eth2, whereas
eth2 doesn't appear in ip -o link show.
I'm joining output of 'ifconfig', 'ip -o link', and 'brctl show'.

The problem surfaced again: xend start just crashes with previous message. If I apply submitted patch, xend start just hang infinitly, and strace shows a futex issue: Process 18743 attached - interrupt to quit futex(0xcce634, FUTEX_WAIT, 1627, NULL) = 0 futex(0xcce608, FUTEX_WAKE, 1) = 0 futex(0xcce660, FUTEX_WAKE, 1) = 1 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 write(19, "\2\0\0\0\0\0\0\0\304\0\0\0009\0\0\0", 16) = 16 write(19, "/vm/2cc873ba-81ea-4a3e-a6bc-15e9"..., 57) = 57 futex(0xcce634, FUTEX_WAIT, 1641, NULL) = 0 futex(0xcce608, FUTEX_WAKE, 1) = 0 futex(0xcce660, FUTEX_WAKE, 1) = 1 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 write(19, "\7\0\0\0\0\0\0\0\304\0\0\0\2\0\0\0", 16) = 16 write(19, "T\0", 2) = 2 futex(0xcce634, FUTEX_WAIT, 1655, NULL) = 0 futex(0xcce608, FUTEX_WAKE, 1) = 0 futex(0xcce660, FUTEX_WAKE, 1) = 1 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 write(19, "\6\0\0\0\0\0\0\0\0\0\0\0\1\0\0\0", 16) = 16 write(19, "\0", 1) = 1 futex(0xcce634, FUTEX_WAIT, 1669, NULL) = 0 futex(0xcce608, FUTEX_WAKE, 1) = 0 futex(0xcce660, FUTEX_WAKE, 1) = 1 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL) = 0 write(19, "\2\0\0\0\0\0\0\0\313\0\0\0009\0\0\0", 16) = 16 write(19, "/vm/2cc873ba-81ea-4a3e-a6bc-15e9"..., 57) = 57 futex(0xcce634, FUTEX_WAIT, 1683, NULL) = 0 futex(0xcce608, FUTEX_WAKE, 1) = 0 futex(0xcce660, FUTEX_WAKE, 1) = 1 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 futex(0xb18840, FUTEX_WAKE, 1) = 0 rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0 futex(0xcce660, FUTEX_WAIT, 2, NULL <unfinished ...> It may be related to the fact I had to use kill -9 on processus resulting from previous run, tough. -- Guillaume Rousse Moyens Informatiques - INRIA Futurs Tel: 01 69 35 69 62 ^ permalink raw reply [flat|nested] 2+ messages in thread
