Re: [Xen-devel] Remus stopped with full protection

[张铭嘉 <zhangninja@xxxxxxxxx>]

Thank you very much for your reply.

I create hvm using spicified remus configuration file(add 'tap:remus'):

[root@server1 img]# xm list

Name                                        ID   Mem VCPUs      State   Time(s)

Domain-0                                     0  2046     8     r-----   1505.3

Rhel5-hvm1                                   2   512     1     ------     28.2

The state of HVM first appears as 'r',then after a while it turns into 'no status' like above.Since Remus claims that it will will block writes to disk until I start the remus script, so I guess this is the normal condition.(I tested the image with common operation like 'xm create' without using "tap:remus"  and logging in with vnc. it is ok)

Following is the contents of xend.log since I create a HVM and run remus script. it seems that there is no infor about running '#remus myvm backuphost' but only infor on creating hvm. 

I notice that there is an error "AttributeError: 'NoneType' object has no attribute 'memory_sharing'" at line 2483. I don't know whether it is the reason that causes remus failed. Maybe I should fix this problem first.

Brendan has posted "HVM live migration error, probably related to 20691:054042ba73b6 " on 21, Jan. The problem is much like that I encountered, yet the version of my xen-unstable is 20550.
