Title:
PowerNV: No rate limit for kernel error "KVM can't copy data from"
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Yakkety:
Fix Committed
Bug description:
== Comment: #0 - MIKHAIL S. MEDVEDEV <mmedv...@us.ibm.com> - 2017-02-03
14:40:58 ==
---Problem Description---
I am experiencing a problem with KVM on Power with a symptom of "KVM can't
copy data" message being spammed to kern.log at about 100000 messages a second.
Apart from original problem that triggers the error, the printk is a problem on
its own. System might run out of space for logs, and would have high CPU load
caused by journald.
This bug is to address an absence of rate limiter on printk at
https://github.com/torvalds/linux/blob/f64e8084c94bb0449177364856d8117e2f14c4c0/arch/powerpc/kvm/book3s_64_mmu.c#L268
Maybe wrapping the printk in printk_ratelimit() is all that is
required?
if(printk_ratelimit()){
printk("KVM can't copy");
}

---uname output---
4.8.0-34-generic #36~16.04.1-Ubuntu SMP Wed Dec 21 18:53:20 UTC 2016 ppc64le
ppc64le ppc64le GNU/Linux
Machine Type = KVM guest on P8 8247 21L
---Debugger---
A debugger is not configured
---Steps to Reproduce---
1. Deploy OpenStack with devstack
2. Run simultaneously between 4 and 6 instances of a script that
- boots a VM (openstack server create)
- immediately creates the backup of the VM (openstack server backup
create)
This is not a very good way to reproduce it. I am still unable to
reproduce the problem just by using libvirt and qemu.

"KVM can't copy data from" error is being logged at very high rate
by kernel. rate limiting this error should fix this issue.
