qvm-service
NAME
qvm-service - manage (Qubes-specific) services started in VM
Date
2012-05-30
SYNOPSIS
qvm-service [-l] <vmname> qvm-service [-e|-d|-D] <vmname> <service>
OPTIONS
-h, --help
Show this help message and exit
-l, --list
List services (default action)
-e, --enable
Enable service
-d, --disable
Disable service
-D, --default
Reset service to its default state (remove from the list). Default state means "lets VM choose" and can depend on VM type (NetVM, AppVM etc).
SUPPORTED SERVICES
This list can be incomplete as VM can implement any additional service without knowledge 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 default 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.
crond
Default: disabled
Enable CRON service. To have cron jobs persist across reboots, /var/spool/cron is bind-mounted from /rw/bind-dirs. To override this see Bind-Dir Instructions )
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.
