Hi On one my physical server (Red Hat Enterprise Linux 5 with xen) i have 10 virtual machines running. Two days ago, suddenly, my net in which are connected all my servers (physical and virtual) started to go more more slowly. I noticed that if I turn off some my virtual machines on xen server, all going on and i didn''t have slowness problem anymore. With a xm dmesg on the physical server that hosts all my vms, I read this: (XEN) (file=memory.c, line=74) Could not allocate order=0 extent: id=0 memflags=0 (0 of 64) I googled a bit but i didn''t find any info about this error. I haven''t still checked vms that I turned off (''cause in this moment I can''t) and obviously i don''t know if there''s a specific problem on some vm. But I''m asking you to know if the error messages printed above is related to a known xen error. Thanks for your help in advance.
