|
SUPPORTED SERVICES
|
|
------------------
|
|
|
|
This list can be incomplete as VM can implement any additional service without knowlege of qubes-core code.
|
|
|
|
meminfo-writer
|
|
Default: enabled everywhere excluding NetVM
|
|
|
|
This service reports VM memory usage to dom0, which effectively enables dynamic memory management for the VM.
|
|
|
|
*Note:* this service is enforced to be set by dom0 code. If you try to remove it (reset to defult state), will be recreated with the rule: enabled if VM have no PCI devices assigned, otherwise disabled.
|
|
|
|
qubes-dvm
|
|
Default: disabled
|
|
|
|
Used internally when creating DispVM savefile.
|
|
|
|
qubes-firewall
|
|
Default: enabled only in ProxyVM
|
|
|
|
Dynamic firewall manager, based on settings in dom0 (qvm-firewall, firewall tab in qubes-manager). This service is not supported in netvms.
|
|
|
|
qubes-network
|
|
Default: enabled only in NetVM and ProxyVM
|
|
|
|
Expose network for other VMs. This includes enabling network forwarding, MASQUERADE, DNS redirection and basic firewall.
|
|
|
|
qubes-netwatcher
|
|
Default: enabled only in ProxyVM
|
|
|
|
Monitor IP change notification from NetVM. When received, reload qubes-firewall service (to force DNS resolution). This service makes sense only with qubes-firewall enabled.
|
|
|
|
qubes-update-check
|
|
Default: enabled
|
|
|
|
Notify dom0 about updates available for this VM. This is shown in qubes-manager as 'update-pending' flag.
|
|
|
|
cups
|
|
Default: enabled only in AppVM
|
|
|
|
Enable CUPS service. The user can disable cups in VM which do not need printing to speed up booting.
|
|
|
|
cron
|
|
Default: disabled
|
|
|
|
Enable CRON service.
|
|
|
|
network-manager
|
|
Default: enabled in NetVM
|
|
|
|
Enable NetworkManager. Only VM with direct access to network device needs this service, but can be useful in ProxyVM to ease VPN setup.
|
|
|
|
ntpd
|
|
Default: disabled
|
|
|
|
Enable NTPD service. By default Qubes calls ntpdate every 6 minutes in selected VM (aka ClockVM), then propagate the result using qrexec calls. Enabling ntpd *do not* disable this behaviour.
|
|
|
|
qubes-yum-proxy
|
|
Deprecated name for qubes-updates-proxy.
|
|
|
|
qubes-updates-proxy
|
|
Default: enabled in NetVM
|
|
|
|
Provide proxy service, which allow access only to yum repos. Filtering is done based on URLs, so it shouldn't be used as leak control (pretty easy to bypass), but is enough to prevent some erroneous user actions.
|
|
|
|
yum-proxy-setup
|
|
Deprecated name for updates-proxy-setup.
|
|
|
|
updates-proxy-setup
|
|
Default: enabled in AppVM (also in templates)
|
|
|
|
Setup yum at startup to use qubes-yum-proxy service.
|
|
|
|
*Note:* this service is automatically enabled when you allow VM to access yum proxy (in firewall settings) and disabled when you deny access to yum proxy.
|
|
|
|
disable-default-route
|
|
Default: disabled
|
|
|
|
Disables the default route for networking. Enabling this service will prevent the creation of the default route, but the VM will still be able to reach it's direct neighbors. The functionality is implemented in /usr/lib/qubes/setup-ip.
|
|
|
|
disable-dns-server
|
|
Default: disabled
|
|
|
|
Enabling this service will result in an empty /etc/resolv.conf. The functionality is implemented in /usr/lib/qubes/setup-ip.
