<p style="padding:0 0 0 0; margin:0 0 0 0;">Ahoj,<br />
<br />
není to problém virt-manageru, ale hlavně libvirt. Nespustí se hypervisor libvirt qemu:///system, jak je v logách níže a virt-manager se nemá k čemu připojit. Libvirt chodí jen na OpenVZ šablonách distribuce Alpine Linux, Debian 8 a CentOS 7.1, viz. KB https://kb.vpsfree.cz/navody/vps/kvm.<br />
<br />
Jinak Qemu/KVM chodí například na Debian 9 či Ubuntu 16.04, jen se musí ovládat pomocí init skriptů, místo libvirt (virt-manageru).<br />
<br />
Renda<br />
<br />

<div>Naistaluju qemu, dokonce i spustím image pomocí konfiguračního souboru. Když ale zkouším virt-amanger (po nainstalování všech dependencies, pro Centos viz KB KVM / Centos), tak virt-manager padá s nic neříkající chybou. Kompletní debug:</div>

<div>Vypadá to, že na něco nedostane odpověď "ret is None" .... ale netuším na co. </div>
<div>Jak v ArchLinuxu tak i v Centosu jsem našel tythle hlášky:</div>
<div>
<div><font face="monospace, monospace">Oct 6 17:04:35 majestatix libvirtd: 2017-10-06 15:04:35.371+0000: 1420: warning : virNumaGetNodeCPUs:276 : NUMA topology for cell 0 is not available, ignoring</font></div>

<div>Ale netuším, jestli to s tím souvisí. Nemáte někdo nějakou radu co dál prosím? Vzhledem k tomu, že jsem ke stejnému výsledku dospěl jak na Centos tak i na Arch LInux, tak myslím že problém bude někde v nastavení VPSky? Nebo se pletu? </div>
<div>Díky za tipy jak dál.</div>
