[Xen-API] XCP 1.1 and the DVD CPU Usage Bug in XenServer 5.6
We're seeing the same issue as described in the following post: http://forums.citrix.com/thread.jspa?threadID=266744&start=30&tstart=0Basically the CPU load on the servers is extremely high and the cause is the cdrommon proc.
Citrix released a fix to this problem for XenServer 5.6 here: http://support.citrix.com/article/CTX126919But that won't work under XCP 1.1 for obvious reasons (kernel version mismatch). A couple of questions for any of those of you that may be knowledgeable concerning building kernel drivers under XCP.
1. Is there a way to verify that the patch didn't make it into XCP 1.1? The ata_generic module reports that it is version 2.15 # modinfo ata_generic filename: /lib/modules/220.127.116.11-0.7.1.xs18.104.22.1687.170596xen/kernel/drivers/ata/ata_generic.ko version: 0.2.15In theory that's the same version that was released as the patched driver. I definitely have the TEAC CD/DVD drives and I'm definitely hitting the bug so it doesn't look like the patch made it into XCP 1.1.
# cat /proc/ide/hda/model DV-28E-V 2. How difficult would it be to recompile the patched driver under XCP? Citrix released the src, including a spec file and a Makefile, to the patch along with the binary. _______________________________________________ xen-api mailing list xen-api@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/mailman/listinfo/xen-api
