Hi~
Anyone have comments about this module?
Hi Chen:
I will take a look at this series.
Sorry for slow reply due to CNY and extend leave.
OK, waiting your comments~ Thanks~
Two general questions:
- if it can detect more than network stall, it should not belong to /net
This module use network connection status to detect all the issue(Host to Guest/Host to Host/Host to Admin...).
The target is more than network but all use network way. So it is looks a tricky problem.
Ok.
- need to convince libvirt guys for this proposal, since usually it's the duty of
upper layer instead of qemu itself
Yes, It looks a upper layer responsibility, but In the cover latter I have explained the reason why we need this in Qemu.
try to make this module as simple as possible. This module give upper layer software a new way to connect/monitoring Qemu.
And due to all the COLO code implement in Qemu side, Many customer want to use this FT solution without other dependencies,
it is very easy to integrated to real product.
Thanks
Zhang Chen
I would like to hear from libvirt about such design.
Hi Jason,
OK. I add the libvirt mailing list in this thread.
The full mail discussion and patches:
