Re: virtual drive performance
Hi again,
just today an issue I've thought to be resolved popped up again. We backup
the machine by doing:
virsh snapshot-create-as --domain domain --name backup --no-metadata
--atomic --disk-only --diskspec hda,snapshot=external
# backup hda.qcow2
virsh blockcommit domain hda --active --pivot
Every now and then this process fails with the following error message:
error: failed to pivot

Re: 答复: virtual drive performance
Just a little catch-up. This time I was able to resolve the issue by doing:
virsh blockjob domain hda --abort
virsh blockcommit domain hda --active --pivot
Last time I had to shut down the virtual machine and do this while being
offline.
Thanks Wang for your valuable input. As far as the memory goes, there's
plenty of head room:

lme4 install error
Dear all,
I'm trying to install lme4 (after having installed R 2.4.0 from source, and
having installed the latest Matrix package). lme4 fails with the following

Re: virtual drive performance
Hi
a small update on this. I just migrated the vm from the site to my laptop
and fired it up. The exact same xml configuration (except file paths and
such) starts up and bursts with 50Mb/s to 115Mb/s in the guest. This allows
only one reasonable answer: the cpu on my laptop is somehow better suited
to emulate IO than the CPU built into the host on site. The host there is a

答复: virtual drive performance
mybe this is because you physic host memory is small
then this will Causing instability of the virtual machine
But I'm just guessing
You can try to increase your memory

Hi,
different day, same issue.. cronjob runs and fails:

virsh blockcommit fails regularily (was: virtual drive performance)
Hi,
a small update on this. We have migrated the virtualized host to use the
virtio drivers and now the drive performance is improved so that we can see
a constant transfer rate. Before it used to be the same rate but regularly
dropped to a few bytes/sec for a few seconds and then was fast again.
However we still observe that the following fails regularily:
$ virsh snapshot-create-as --domain

[LLVMdev] RFC: LLVM incubation, or requirements for committing new backends
Tom,
I think it might be productive to fork this thread to discuss making the requirements for upstreaming a new LLVM target more explicit and open. I'd also like to gauge interest in an idea I've discussed privately with a few community members, namely the concept of having a semi-official "incubation" system whereby proposed backends could get a trial run before becoming part
