Subject: rpc: Allow up to 256K records to be returned per domain from virConnectGetAllDomainStats.
X-Git-Tag: v3.4.0-rc1~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4c70a6f8745714d59d4d66475f639873a0c8e191;p=thirdparty%2Flibvirt.git

rpc: Allow up to 256K records to be returned per domain from virConnectGetAllDomainStats.

The number of records that virConnectGetAllDomainStats can return per
domain is currently limited to 4096.  This is quite low -- for
example, a single guest with ~320 disks will hit this limit.  This
increases the limit to make it much larger.  Note that
VIR_NET_MESSAGE_MAX still protects the total message size in the case
where there are many domains and many disks per domain.

I tested this using a guest with 500 disks with no issues.
