Thank you
and man errno ,there is no match or map between num,say 104 and
consist ,say EBADMSG, or maybe some book more helpful
another question
i am confused about how to use shadow mechanism ,that is, when live
migration, after shutdown VM,and XEN_DOMCTL_SHADOW_OP_CLEAN, how to make VM
remain in shadow mode XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY? i have
modified the code to try to make it as follows
if ( !(xc_shadow_control(xc_handle, dom,
XEN_DOMCTL_SHADOW_OP_OFF,
NULL, 0, NULL, 0, NULL) >= 0 &&
xc_shadow_control(xc_handle, dom,
XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY,
NULL, 0, NULL, 0, NULL) >= 0) )
but it seems not to work , and how to do it ,or any help
Thanks

hi
i try to modify code of xc_domain_save.c
and there is error, comes out from ERROR("Error when writing to state
file (5)" " (errno %d)", errno);
i am confused about where is the errno defined ,and what does variable
num mean? say errno=104 or errno=26 or some else
Error numbers are a C library feature. If you're running Linux, check
whether you have installed the base development manual pages and try
'man errno'. Or see a good book on C programming.
good luck,
Daniel
