Re: Performance base de données

Les VM sont chacune sur un LV LVM elles utilisent virtio.
Par contre il y'a quelque chose de bizarre dans la configuration:

 # virsh edit zabbix-db-1
 <domain type='kvm'>
 <name>zabbix-db-1</name>
 <uuid>xxxxx-xxxxx-xxxxx-xxxxx</uuid>
 <memory>16777216</memory>
 <currentMemory>16777216</currentMemory>
 <vcpu>6</vcpu>
 <os>
 <type arch='x86_64' machine='pc-1.0'>hvm</type>
 <boot dev='hd'/>
 </os>
 <features>
 <acpi/>
 </features>
 <clock offset='utc'/>
 <on_poweroff>destroy</on_poweroff>
 <on_reboot>restart</on_reboot>
 <on_crash>destroy</on_crash>
 <devices>
 <emulator>/usr/bin/kvm</emulator>
 <disk type='file' device='disk'>
 <driver name='qemu' type='raw'/>
 <source file='/dev/kvm-6-vg/zabbix-db-1'/>
 <target dev='vda' bus='virtio'/>
 <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
 </disk>
 <controller type='ide' index='0'>
 <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/>
 </controller>
 <interface type='bridge'>
 <mac address='x:x:x:x'/>
 <source bridge='br0'/>
 <model type='virtio'/>
 <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
 </interface>
 <input type='mouse' bus='ps2'/>
 <graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1'>
 <listen type='address' address='127.0.0.1'/>
 </graphics>
 <video>
 <model type='cirrus' vram='9216' heads='1'/>
 <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
 </video>
 <memballoon model='virtio'>
 <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
 </memballoon>
 </devices>
 </domain>

Ce qui me choque c'est controller type='ide' normal?
