Hi list, I''m trying out Debian Squeeze with XEN 4.0.1 on a Dell m610 blade. Everything is installed from the squeeze repository, except the dom0 kernel, which would not boot on the m610, so I compiled 2.6.32.25 from jeremy 11/11-2010. (http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=summary) Everything looks good, except these messages, which I''ve not been able to explain: [ 16.651781] XENBUS: Unable to read cpu state [ 16.651968] XENBUS: Unable to read cpu state [ 16.652156] XENBUS: Unable to read cpu state etc... Removing cpu''s work, but when I try to add cpu''s: root@node0106:/# xm vcpu-set 15 15 [2010-11-24 12:22:49 26321] INFO (XendDomainInfo:1987) Set VCPU count on domain squeezetest01 to 15 but cpu''s are still in paused mode: Name ID VCPU CPU State Time(s) CPU Affinity squeezetest01 15 0 12 -b- 18.9 any cpu squeezetest01 15 1 4 -b- 0.6 any cpu squeezetest01 15 2 6 -b- 0.9 any cpu squeezetest01 15 3 15 -b- 0.8 any cpu squeezetest01 15 4 8 -b- 0.8 any cpu squeezetest01 15 5 - --p 0.1 any cpu squeezetest01 15 6 - --p 0.1 any cpu squeezetest01 15 7 - --p 0.1 any cpu This also shows on the VM: root@squeezetest01:~# cat /sys/devices/system/cpu/offline 5-14 On the VM I''ve tried both the stock squeeze kernel linux-image-2.6.32-5-xen-amd64 and jeremys 2.6.32.25 - both have this problem. Any ideas are greatly appreciated! ;-) Regards Kristoffer _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hello, On my debian squeeze, I think I got the same issue. Starting a server with 4 vcpus (vcpus=4 in config file), I can "vcpu-set" 2 vcpus for this server successfully, but I can''t rollback to 4 vcpu. Xend Log file says : [2010-11-24 13:01:23 19542] INFO (XendDomainInfo:1987) Set VCPU count on domain testvm to 2 [2010-11-24 13:01:48 19542] INFO (XendDomainInfo:1987) Set VCPU count on domain testvm to 4 But cpus are offline in domU/paused in dom0. I also got the "XENBUS: Unable to read cpu state" error.
