Description of problem:
  The guest is a flesh installed,and then kernel is updated to the latest 5.4-z (-164.2.1) version.
   i386 guest works fine,while x86_64 guest  cost about 8 minutes before the desktop come up again. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.start RHEL5u4 x86_64 guest :
  /usr/libexec/qemu-kvm -m 1024 -smp 2 -drive file=/data/images/t77/08-5u4.64.raw,if=ide  -net nic,model=e1000,macaddr=00:01:02:58:5F:04 -net tap -monitor stdio -vnc :2 -no-kvm-pit-reinjection -rtc-td-hack -notify all -boot c -name 5u4-64 -uuid 791f094e-1530-48c4-a062-b094903d4f71
2. echo disk > /sys/power/state
3. Use the cli in step1 to start guest again.

Can you please retest on newer kvm-83-142 ?

Comment 3 Gleb Natapov 2010-01-05 09:51:23 UTC
I believe this is the same problem as BZ 539521.

Comment 4 Glauber Costa 2010-01-20 17:39:44 UTC
I can't reproduce this issue, because I can't even put the machine to disk.
What I get is this:

Stopping tasks:
 stopping tasks timed out after 120 seconds (1 tasks remaining):
Restarting tasks...<6> Strange, khungtaskd not stopped

However, by code inspection, I have a slight idea of what's going on. I am
brewing a new scratch build that will be ready shortly at:


Comment 5 Glauber Costa 2010-01-20 20:39:34 UTC
Ok... according to Gleb, that was an unrelated regression introduced in 5.5

So I am building another rpm ontop of 5.4.z

To be ready shortly. Here it is:


Comment 6 Suqin Huang 2010-01-21 10:22:55 UTC
repeat 10 times, can not reproduce with new built package.
guest: rhel5.4-x86_64
1. can access network after resume.
2. can edit files after resume.

/usr/libexec/qemu-kvm -drive file=/root/rhel5.4-64-ide.bak,if=ide  -no-hpet -rtc-td-hack -smp 8 -m 4G -uuid `uuidgen` -net nic,model=e1000,macaddr=00:A6:78:FA:0D:95,vlan=0 -net tap,vlan=0,script=/etc/qemu-ifup -cpu qemu64,+sse2 -boot c -vnc :6  -monitor stdio -name 5.4-64 -no-kvm-pit-reinjection
