ps sort cpu load
Description of problem:
Bad perfomance in virt-install (network boot)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. virt-install --name fedoratestday --ram 1024 --disk path=/home/brain/fedoratestday.img,size=10 --location http://download.fedoraproject.org/pub/fedora/linux/development/19/x86_64/os/ or in virt-manager
3. Enter language
4. Calculate dependence
Some letters aren't shown and bad performance (100% load cpu)
beta dvd|netinst works correctly
Proposed as a Freeze Exception for 19-final by Fedora user ignatenkobrain using the blocker tracking app because:
Virtualization load from network imho shall work
I can't reproduce this exactly. CPU load does seem to be generally higher in the kernel pair boot case where anaconda itself is retrieved from the remote repo, but I don't ever see it 'stick' at 100%.
if I do a kernel pair boot and pass 'inst.repo=http://dl.fedoraproject.org/pub/fedora/linux/development/19/x86_64/os/' then I see 100% CPU use for a short time during installer init, then it drops, then spikes to 100% for a while longer while 'calculating dependencies', then drops to almost 0% as long as I just sit on hub. when I start an install it again spikes to 100% a couple of times while partitioning, then when it settles into package installation, it tends to bounce between 20-30% and 100%. But at no point does it just 'stick' at 100% usage, and the times when it's at 100% seem to be reasonably related to actual operations happening at that point in time.
Given lack of reproducer in Comment #2 and no follow up, closing. If someone can still reproduce, please reopen.
